Electronic storage 16 may include one or more of optically readable storage media (e.g., optical disks, etc.), magnetically readable storage media (e.g., magnetic tape, magnetic hard drive, floppy drive, etc.), electrical charge-based storage media (e.g., EEPROM, RAM, etc.), solid-state storage media (e.g., flash drive, etc.), and/or other electronically readable storage media. Electronic storage 16 may store software algorithms, information determined by processor 22, information received via controller 20, and/or other information that enables first computing platform 12 to function properly. Electronic storage 16 may be a separate component within first computing platform 12, or electronic storage 16 may be provided integrally with one or more other components of first computing platform 12 (e.g., processor 22).

(21) The electronic display 18 may be configured to generate a visual display of views rendered by processor 22 and/or other components of first computing platform 12. The electronic display 18 may include one or more of a television, a monitor, a touchscreen, a projection screen and/or projector, and/or other electronic displays. Although electronic display 18 is illustrated in FIG. 1 as a single component, in some implementations electronic display 18 may include a plurality of separate displays cooperating to generate visual displays rendered by first computing platform 12 to provide the videogame to the user.

(22) In some implementations, electronic display 18 may be associated with one or more sound production devices (e.g., speakers, amplifiers, and/or other sound production devices). The sound production devices (not shown) may be configured to produce sounds in accordance with the videogame and/or in coordination with the visual displays generated by electronic display 18. The one or more sound production devices may be provided integrally with electronic display 18 and/or separately from electronic display 18. The one or more sound production devices may be in operative communication with electronic display 18 and/or processor 22 to receive signals dictating the sounds generated by the sound production devices.

(23) The controller 20 may be configured to enable a user to input control inputs to first computing platform 12. This may enable the user to control one or more aspects of the videogame being provided to the user by first computing platform 12, to control operation of one or more of the components of first computing platform 12 (e.g., power, volume, brightness, and/or other aspects of operation), and/or provide other types of interaction between the user and first computing platform 12. In order to enable the input of control inputs, controller 20 may include one or more of a switch, a button a knob, a lever, an analog stick, a position, velocity, and/or acceleration detector, a direction pad, a microphone, a keypad, a number pad, and/or other devices enabling the input of control inputs by the user. The controller 20 may include one or more feedback devices through which information is communicated to the user from first computing platform 12. By way of non-limiting example, controller 20 may include a tactile feedback device, a sound generating device, a visual display generating device, and/or other feedback devices. The controller 20 may be operatively linked for communication with one or more of electronic storage 16, electronic display 18, processor 22, and/or other components of first computing platform 12.

(24) Processor 22 is configured to provide information processing capabilities in first computing platform 12. As such, processor 22 may include one or more of a digital processor, an analog processor, a digital circuit designed to process information, an analog circuit designed to process information, a state machine, and/or other mechanisms for electronically processing information. Although processor 22 is shown in FIG. 1 as a single entity, this is for illustrative purposes only. In some implementations, processor 22 may include a plurality of processing units. These processing units may be physically located within the same device, or processor 22 may represent processing functionality of a plurality of devices operating in coordination.

(25) As is shown in FIG. 1, processor 22 may be configured to execute one or more computer program modules. The one or more computer program modules may include one or more of a game module 24, a user module 26, a performance monitoring module 28, a challenge creation module 30, a challenge criteria module 32, a challenge customization module 34, a challenge communication module 36, a challenge access module 38, a challenge monitoring module 40, and/or other modules. Processor 22 may be configured to execute modules 24, 26, 28, 30, 32, 34, 36, 38, and/or 40 by software; hardware; firmware; some combination of software, hardware, and/or firmware; and/or other mechanisms for configuring processing capabilities on processor 22.

(26) It should be appreciated that although modules 24, 26, 28, 30, 32, 34, 36, 38, and 40 are illustrated in FIG. 1 as being co-located within a single processing unit, in implementations in which processor 22 includes multiple processing units, one or more of modules 24, 26, 28, 30, 32, 34, 36, 38, and/or 40 may be located remotely from the other modules. The description of the functionality provided by the different modules 24, 26, 28, 30, 32, 34, 36, 38, and/or 40 described below is for illustrative purposes, and is not intended to be limiting, as any of modules 24, 26, 28, 30, 32, 34, 36, 38, and/or 40 may provide more or less functionality than is described. For example, one or more of modules 24, 26, 28, 30, 32, 34, 36, 38, and/or 40 may be eliminated, and some or all of its functionality may be provided by other ones of modules 24, 26, 28, 30, 32, 34, 36, 38, and/or 40. As another example, processor 22 may be configured to execute one or more additional modules that may perform some or all of the functionality attributed below to one of modules 24, 26, 28, 30, 32, 34, 36, 38, and/or 40.

(27) The game module 24 may be configured to first computing platform 12 to generate a display, sounds, and/or haptic stimulation for the player that enables the player to experience a videogame. For example, if the videogame is a racing videogame, game module 24 may be configured to control the generation of sensory stimulation that mimics the sensory stimulation experienced during vehicular racing in real life. As such, game module 24 may include a physics engine, a rendering engine, and/or other information, instructions, and/or modules configured to generate the sensory stimulation associated with the videogame. The game module 24 may be configured to receive control input (e.g., from controller 20), and to adjust the display, sounds, haptic stimulation, and/or other stimulation generated for the player in accordance with parameters dictated by the videogame. For example, game module 24 may cause an object (e.g., an avatar, a virtual vehicle, aircraft, watercraft, and/or other conveyance, and/or other objects) associated with and/or under control of the player to perform actions in accordance with control input received from the player. To perform the functionality of game module 24 described herein, game module 24 may execute an instance of the videogame, or game module 24 may execute a client application that accesses an instance of the videogame being executed remotely from game module 24 on a server.

(28) The user module 26 may be configured to access and/or manage one or more user profiles associated with players using first computing platform 12. The one or more user profiles may include information stored locally on first computing platform 12 and/or information stored remotely from first computing platform 12 (e.g., on a server). The user profiles may include, for example, information identifying the player (e.g., a username or handle, a number, an identifier, and/or other identifying information), security login information (e.g., a login code or password), game specific account information, subscription information, virtual currency account information (e.g., related to currency held in credit for the player), friend information (e.g., information related to friends of the player), game usage information, and/or other information related to the player.

(29) The performance monitoring module 28 may be configured to quantify performance of a task by the player within the videogame. This may include determining values for a set of performance metrics characterizing the performance of the task by the player. The task may include an action, or set of actions, performed by the player in order to achieve an objective. For example, in a racing game, a task may include completing a portion of a race (e.g., a lap), completing a race, completing a tour (e.g., a collection of races), and/or other tasks. In a fighting and/or shooting game, a task may include defeating a certain opponent (or set of opponents), and/or other tasks. In a role-playing or strategy game, a task may include defeating a certain opponent (or set of opponents), conquering or controlling an area, exploring a place or set of places, and/or other tasks. In a platformer game, a task may include completing a level, clearing a level, and/or other tasks. It will be appreciated that this list of videogame genres and/or potential tasks is not intended to be limiting. For the purposes of this disclosure, a task may include any videogame activity in which a player performs one or more actions to achieve an objective.

(30) The performance metrics of a given task may include variables that quantify the performance of the given task by players of the videogame. Some non-limiting, examples of performance metrics for a task may include time to complete the task, points accumulated during the task, finishing position (e.g., leading or winner, first runner-up, second runner-up, and/or other finishing positions), accuracy (e.g., ratio of hits-to-shots taken, percentage of hits, and/or other accuracy parameters), number of opponents incapacitated, defeated, killed, robbed, avoided, and/or otherwise dealt with, power-ups collected, power-ups used, failures (e.g., lives lost, attempts, and/or other parameters reflecting failure), distance traveled, damage received, damage inflicted, number of allies providing assistance, and/or other parameters. The performance metrics for a performance of the given task may be measured and/or assigned values by performance monitoring module 28 during performance of the given task and/or after performance of the given task by the player within the videogame. To determine values for the performance metrics, performance monitoring module 28 may monitor game module 24 during performance of the given task.

(31) The challenge creation module 30 may be configured to create a challenge within the videogame under the direction of the player. A challenge may include a set of challenge criteria (e.g., challenge parameters, challenge metrics, values for challenge parameters and/or metrics, and/or other criteria). Completing the challenge may require completing the task associated with the challenge as defined by the challenge parameters, under the game parameters dictated by the challenge parameters, while equaling or exceeding the performance required by the values for the set of challenge metrics. The challenge parameters (e.g., the task and/or the game parameters) may correspond to the same parameters present when the player issuing the challenge completed the task. The challenge metrics for the task may correspond to performance metrics determined by performance monitoring module 28 during actual performance of the task by the player issuing the challenge. The challenge metrics for the task may include a subset of the performance metrics.

(32) The values for the challenge metrics for a challenge may be determined based on a previous performance of the task associated with the challenge by the player creating the challenge. For example, if the task includes completing a lap in a racing game, and one of the challenge metrics includes lap time, the value for lap time for the challenge may be the lap time achieved by the player. As another example, if the task includes defeating a boss character, and one of the challenge metrics includes the duration of the fight, the value for fight duration for the challenge may be the duration of the fight in which the player defeated the boss character.

(33) The challenge creation module 30 may be configured such that the player may be automatically prompted to create a challenge. The player may be automatically prompted to create the challenge upon completion of a task, during performance of the task, and/or prior to commencement of the task. The challenge creation module 30 may be configured such that the player requests the creation of a challenge without prompting. The player may request the creation of the challenge prior to attempting the task, during performance of the task, and/or the player may request the creation of the challenge subsequent to completing the task.

(34) In creating a challenge, challenge creation module 30 may determine one or more players that are to receive the challenge. This may be accomplished, for example, via user selection. The challenge creation module 30 may be configured to present an interface to the player through which the player can select other players that are to receive the challenge. The other players may be selected from a set of friends of the player, from a leaderboard, and/or from other lists.

(35) By way of non-limiting example, FIGS. 2-4 illustrate selection by the player of other players to receive the challenge. In particular, FIG. 2 illustrates an interface 42 through which the player can select one or more other players. The interface may be presented to the player, for example, through an electronic display similar to or the same as electronic display 18 (shown in FIG. 1 and described above). The interface 42 may be configured to receive a control input from the player indicating that one of empty player slots 44 should be filled.

(36) If such a control input is received, an interface 46 shown in FIG. 3 may be presented to the player. The interface 46 may be presented to the player, for example through an electronic display similar to or the same as electronic display 18 (shown in FIG. 1 and described above). The interface 46 may present a list 48 of other players to the user, and may be configured to receive selection of one of the players from list 48.

(37) As is shown in FIG. 4, in response to selection of another player from a list similar to or the same as list 48 (shown in FIG. 3 and described above), the selected player may be inserted into one of empty player slots 44. For example, in FIG. 4, interface 42 includes the selected player inserted into filled slot 50.

(38) The challenge criteria module 32 may be configured to associate challenge criteria with a challenge created by the player via challenge creation module 30. For example, the challenge criteria module 32 may associate challenge parameters with the challenge. The challenge parameters may be associated with the challenge based on a record of the task, the game parameters present during performance of the task by the first player, and/or other challenge parameters. These challenge parameters may include one or more parameters determined automatically (e.g., by game module 24 prior to performance of the task by the player creating the challenge) and/or determined based on user-selection (e.g., by selection of the player creating the challenge prior to performance of the task). The record may have been created before, during, or subsequent to, performance of the task by the player creating the challenge. The record may be stored on first computing platform 12, and/or on a server in operative communication with first computing platform 12.

(39) The challenge criteria module 32 may associate challenge metrics with the challenge by assigning a subset of the performance metrics to the challenge as challenge metrics. The subset of the performance metrics assigned to the challenge as challenge metrics may include any one or more of the performance metrics, up to and including all of the performance metrics. The values of the challenge metrics for the challenge may correspond to the values for the performance metrics achieved by the player during performance of the task.

(40) The challenge criteria module 32 may be configured such that the inclusion of one or more of the performance metrics in the challenge metrics is performed automatically (e.g., by static selection rule, based upon performance with respect to the different performance metrics, and/or otherwise selected). The challenge criteria module 32 may be configured such that the inclusion of one or more of the performance metrics in the challenge metrics is performed based in user selection.

(41) FIG. 5 illustrates an interface 52 that displays a challenge 54 to the player. The interface 52 may be presented to the player, for example through an electronic display similar to or the same as electronic display 18 (shown in FIG. 1 and described above). As is shown in interface 52, challenge 54 may include one or more of a title 56, challenge parameters 58, a challenge metric list 60, content 62, and/or other components. The title 56 may provide some description of the task and/or challenge.

(42) The challenge parameters 58 may define the task associated with the challenge. The challenge parameters 58 may define the task by identifying one or more elements of the task that characterize the task. By way of non-limiting example, challenge parameters 58 may identify one or more of a venue 64, an event or objective 66, equipment used 68, a difficulty setting 70, and/or other elements that characterize the task. These elements may correspond to the elements that were present as the player performed (or will be present as the player performs) the task.

(43) The challenge metric list 60 may list the challenge metrics associated with challenge 54. The challenge metric list 60 may present the values for the challenge metrics associated with challenge 54. As was mentioned above, the values may be determined based on performance of the task associated with challenge 54 by the player. By way of non-limiting example, the challenge metrics may include a finishing position, a number of fans (or points, or dollars, or some other metric) earned during the task, and/or other challenge metrics. In the example shown in FIG. 5, challenge metric list 60 includes an extra slot 76, into which a user selected challenge metric may be inserted.

(44) The interface 52 may be configured to receive a request from the player to include another challenge metric in extra slot 76 in challenge metric list 60. Responsive to reception of such a request, an interface 78, as shown in FIG. 6, may be presented to the player. The interface 78 may be presented to the player, for example through an electronic display similar to or the same as electronic display 18 (shown in FIG. 1 and described above). The interface 78 may include a list of performance metrics 80 (illustrated including the following exemplary metrics: metric a 94, metric b 92, metric c 90, metric d 88, metric e 86, metric f 84, and metric g 82), which may be selected by the player for implementation as a challenge metric. For example, list of performance metrics 80 may include one or more of a score for the task, a time to complete the task, a number of speed boosts used during the task, a number of projectiles hit during the task, a number of stationary explosives hit during the task, a number of obstacles hit during the task, a number of shunts hit during the task, and/or other performance metrics. The interface 78 may be configured to receive a selection by the player of one or more of the performance metrics listed in list of performance metrics 80. Responsive to such selection, the selected one or more performance metrics may be included in a challenge. For example, responsive to receipt of a selection in interface 78 of metric e 86, metric e 86 may be included in a challenge similar to or the same as challenge 54 (shown in FIG. 5 and described above).

(45) Referring to FIG. 7, responsive to receipt of selection at interface 78 of a performance metric in a challenge as a challenge metric (e.g., metric e 86), interface 78 may be configured to receive a user selection as to whether the value for the selected performance metric should be used as an upper threshold or a lower threshold in determining whether a subsequent player has completed the challenge, of if the challenge should require an equivalent value for the selected performance metric. For example, responsive to receipt of a selection by the player that the value for the selected performance metric should be used as an upper threshold, the challenge requires other players to exceed the value for the selected performance metric. To receive user selection as to whether the value for the selected performance metric should be used as an upper threshold or a lower threshold, interface 78 may include a field 96 in which the user selection is received.

(46) Responsive to receipt of user selection by the player as to whether the value should be used as an upper or lower threshold, interface 78 may be configured to represent the selection. By way of illustration, FIG. 8 shows a view of interface 78 indicating receipt of a selection that metric e 86 should be included as a challenge metric, and that the value for number of speed boosts used 86 should be used as an upper threshold (e.g., the challenge requires use of a greater number of speed boosts). This is indication is given by indicator 98.

(47) Referring now to FIG. 9, interface 52 is shown, including the user selected challenge metric e 86 in challenge metric list 60. This indicates to other players attempting challenge 54 that number of speed boosts used 86 may be one of the challenge metrics for challenge 54.

(48) Returning to FIG. 1, the challenge customization module 34 may be configured to customize the challenge. The customization provided by challenge customization module 34 may include editing a title of a challenge, adding, removing, and/or editing content associated with the challenge, and/or other customizations. The content added, removed, and/or edited may include one or more text, video, still images, audio, and/or other content.

(49) By way of illustration, interface 52, shown in FIGS. 5 and 9, may be configured to receive user requests to customize challenge 54. For example, interface 52 may be configured to receive user selection of title 56 by the player. Turning to FIG. 10, responsive to reception of such user selection, an interface 100 may be presented to the player. The interface 100 may be presented to the player, for example through an electronic display similar to or the same as electronic display 18 (shown in FIG. 1 and described above). As can be seen in FIG. 10, interface 100 may be configured to receive customization of the title of the challenge.

(50) Referring again to interface 52, shown in FIGS. 5 and 9, interface 52 may be configured to receive user selection of content 62. Turning to FIG. 11, responsive to reception of such user selection of content 62 by the player, an interface 102 may be presented to the player. The interface 102 may be presented to the player, for example through an electronic display similar to or the same as electronic display 18 (shown in FIG. 1 and described above). The interface 102 may be configured to receive customization of content associated with the challenge. It will be appreciated that the illustration of interface 102 as being configured to receive customization of textual content is not intended to be limiting. One or more interfaces may be presented to the player configured to receive customization of a challenge in the form of audio, video, and/or still image content to be associated with the challenge.

(51) Returning to FIG. 1, the challenge communication module 36 may be configured to initiate transmission of a challenge invitation associated with the challenge to one or more other players. This may include initiating transmission of the challenge invitation to computing platform(s) associated with the one or more other players. For example, challenge communication module 36 may initiate transmission of the challenge invitation from first computing platform 12 to second computing platform 14. The challenge invitation may prompt the player receiving the challenge to attempt the challenge and/or may provide the challenge criteria associated with the challenge to second computing platform 14.

(52) The transmission of the challenge invitation may be accomplished via a network, a dedicated line, an electronic message, a micro-blogging service (e.g., as provided by Twitter, and/or other micro-blogging services), a social network (e.g., as provided by Facebook, MySpace, and/or other social networks), a gaming first party communication system (e.g., as provided by Xbox Live, Sony Home, and/or other gaming first party communication systems), and/or other communication media. The challenge communication module 36 may be configured to initiate transmission of the challenge invitation without requiring the player to leave the videogame provided by game module 24 and/or the control environment associated therewith (e.g., as illustrated in FIGS. 2-11).

(53) The media of communication implemented to transmit the challenge invitation from first computing platform 12 to second computing platform 14 may include communication media that is not specific to a particular type of computing platform. For example, a micro-blogging service, a social network, and/or communication media may be platform type agnostic. This may enable challenges to be transmitted and/or accepted between players that participate in the videogame on different platform types. For example, first computing platform 12 may include a first type of gaming console while second computing platform 14 may include second type of gaming console. As another example, one or the other of first computing platform 12 or second computing platform 14 may include a personal computer (e.g., desktop, laptop, or other personal computer). Types of gaming consoles may include, for example, Nintendo Wii, Nintendo DS, Sony PlayStation PSP, Sony PlayStation 2, Sony PlayStation 3, Microsoft Xbox 360, and/or other gaming console types.

(54) The second computing platform 14 may include a game console, such as Xbox 360 game console, the PlayStation3 game console, the Wii game console, and/or other game consoles. This is not intended to be limiting. In some implementations, second computing platform 14 may include one or more other consumer computing platforms, such as, a desktop computer, a laptop computer, a handheld computer, a personal gaming device, a NetBook, a SmartPhone, and/or other computing platforms. second computing platform 14 may include one or more of electronic storage 104, an electronic display 106, a controller 108, one or more processors 110, and/or other components.

(55) Electronic storage 104 may comprise electronic storage media that electronically stores information. The electronic storage media of electronic storage 104 may include one or both of system storage that is provided integrally (i.e., substantially non-removable) with second computing platform 14 and/or removable storage that is removably connectable to second computing platform 14 via, for example, a port (e.g., a USB port, a firewire port, etc.) or a drive (e.g., a disk drive, etc.). Electronic storage 104 may include one or more of optically readable storage media (e.g., optical disks, etc.), magnetically readable storage media (e.g., magnetic tape, magnetic hard drive, floppy drive, etc.), electrical charge-based storage media (e.g., EEPROM, RAM, etc.), solid-state storage media (e.g., flash drive, etc.), and/or other electronically readable storage media. Electronic storage 104 may store software algorithms, information determined by processor 110, information received via controller 108, and/or other information that enables second computing platform 14 to function properly. Electronic storage 104 may be a separate component within second computing platform 14, or electronic storage 104 may be provided integrally with one or more other components of second computing platform 14 (e.g., processor 110).

(56) The electronic display 106 may be configured to generate a visual display of views rendered by processor 110 and/or other components of second computing platform 14. The electronic display 18 may include one or more of a television, a monitor, a touchscreen, a projection screen and/or projector, and/or other electronic displays. Although electronic display 106 is illustrated in FIG. 1 as a single component, in some implementations electronic display 106 may include a plurality of separate displays cooperating to generate visual displays rendered by second computing platform 14 to provide the videogame to the user.

(57) In some implementations, electronic display 106 may be associated with one or more sound production devices (e.g., speakers, amplifiers, and/or other sound production devices). The sound production devices (not shown) may be configured to produce sounds in accordance with the videogame and/or in coordination with the visual displays generated by electronic display 106. The one or more sound production devices may be provided integrally with electronic display 106 and/or separately from electronic display 106. The one or more sound production devices may be in operative communication with electronic display 106 and/or processor 110 to receive signals dictating the sounds generated by the sound production devices.

(58) The controller 108 may be configured to enable a user to input control inputs to second computing platform 14. This may enable the user to control one or more aspects of the videogame being provided to the user by second computing platform 14, to control operation of one or more of the components of second computing platform 14 (e.g., power, volume, brightness, and/or other aspects of operation), and/or provide other types of interaction between the user and second computing platform 14. In order to enable the input of control inputs, controller 108 may include one or more of a switch, a button a knob, a lever, an analog stick, a position, velocity, and/or acceleration detector, a direction pad, a microphone, a keypad, a number pad, and/or other devices enabling the input of control inputs by the user. The controller 108 may include one or more feedback devices through which information is communicated to the user from second computing platform 14. By way of non-limiting example, controller 108 may include a tactile feedback device, a sound generating device, a visual display generating device, and/or other feedback devices. The controller 108 may be operatively linked for communication with one or more of electronic storage 104, electronic display 106, processor 110, and/or other components of second computing platform 14.

(59) Processor 110 is configured to provide information processing capabilities in second computing platform 14. As such, processor 110 may include one or more of a digital processor, an analog processor, a digital circuit designed to process information, an analog circuit designed to process information, a state machine, and/or other mechanisms for electronically processing information. Although processor 110 is shown in FIG. 1 as a single entity, this is for illustrative purposes only. In some implementations, processor 110 may include a plurality of processing units. These processing units may be physically located within the same device, or processor 110 may represent processing functionality of a plurality of devices operating in coordination.

(60) As is shown in FIG. 1, processor 110 may be configured to execute one or more computer program modules. The one or more computer program modules may include one or more of a game module 112, a user module 114, a performance monitoring module 116, a challenge creation module 118, a challenge criteria module 120, a challenge customization module 122, a challenge communication module 124, a challenge access module 126, a challenge monitoring module 128, and/or other modules. Processor 110 may be configured to execute modules 112, 114, 116, 118, 120, 122, 124, 126, and/or 128 by software; hardware; firmware; some combination of software, hardware, and/or firmware; and/or other mechanisms for configuring processing capabilities on processor 110.

(61) It should be appreciated that although modules 112, 114, 116, 118, 120, 122, 124, 126, and 128 are illustrated in FIG. 1 as being co-located within a single processing unit, in implementations in which processor 110 includes multiple processing units, one or more of modules 112, 114, 116, 118, 120, 122, 124, 126, and/or 128 may be located remotely from the other modules. The description of the functionality provided by the different modules 112, 114, 116, 118, 120, 122, 124, 126, and/or 128 described below is for illustrative purposes, and is not intended to be limiting, as any of modules 112, 114, 116, 118, 120, 122, 124, 126, and/or 128 may provide more or less functionality than is described. For example, one or more of modules 112, 114, 116, 118, 120, 122, 124, 126, and/or 128 may be eliminated, and some or all of its functionality may be provided by other ones of modules 112, 114, 116, 118, 120, 122, 124, 126, and/or 128. As another example, processor 110 may be configured to execute one or more additional modules that may perform some or all of the functionality attributed below to one of modules 112, 114, 116, 118, 120, 122, 124, 126, and/or 128.

(62) The game module 112, user module 114, and performance monitoring module 116 of processors 110 operate in substantially the same manner as game module 24, user module 26, and performance monitoring module 28 of processor 22, respectively. As such, a separate description of the functionality of modules game module 112, user module 114, and performance monitoring module 116 will not be provided herein in detail.

(63) The challenge communication module 124 may be configured to receive the challenge invitation transmitted from first computing platform 12. The challenge communication module 124 may be configured to convey the challenge invitation to the player associated with second computing platform 14. For example, FIG. 12 illustrates an interface 130 configured to convey the challenge invitation to the player associated with second computing platform 14. The interface 130 may be presented to the player, for example through an electronic display similar to or the same as electronic display 106 (shown in FIG. 1 and described above). The interface 130 may present the challenge invitation 132 to the player. The interface 130 may be configured to receive a user selection of challenge invitation 132 by the player. Responsive to challenge invitation 132 by the player, the player may be given the opportunity to attempt the challenge associated with challenge invitation 132, save challenge invitation 132 for a later attempt, reject challenge invitation 132, and/or take other actions with respect to challenge invitation 132.

(64) The representation of challenge invitation 132 in FIG. 12 is not intended to be limiting. The challenge invitation 132 conveyed to the player via, for example, electronic display 106 may include content associated with the challenge, challenge metric(s) associated with the challenge, value(s) for the challenge metric(s) associated with the challenge, a definition of the task associated with the challenge, and/or other challenge criteria.

(65) The challenge access module 126 may be configured receive acceptance of the challenge from the player (e.g., through interface 130 shown in FIG. 12 and described above). Responsive to acceptance of the challenge from the player, challenge access module 126 may be configured to provide access to the challenge for the player so that the player can attempt to complete the task within the videogame. This may include prompting game module 112 to present the task to the player so that the player can attempt to complete the task.

(66) It will be appreciated that in some cases, challenge criteria of a received challenge may require access to content that has not previously been accessible to the player within the videogame. The player may not have played far enough into the game (e.g., through completing levels, acquiring skills, traveling to virtual locations, and/or otherwise accessing content within the game) to reach content required by the challenge criteria of the challenge. Similarly, the player may not have acquired equipment, skills, content, allies, and/or other resources that form part of the task definition. This may result in content associated with the challenge being locked to the player upon receipt and acceptance of the challenge. For example, within a racing game, a player may not have unlocked a racetrack, a car, and/or other content. Within a fighting game, a player may not have unlocked a battle or fight venue, a weapon, a boss fight, and/or other content. Other examples also exist. In cases where the player has unlocked all of the content associated with a challenge, the player may not have unlocked the content at a difficulty setting corresponding to the challenge. For instance, the player may have unlocked the content while playing on an easy setting, while the task definition associated with the challenge may require a difficulty setting to be higher (e.g., more difficult).

(67) The challenge access module 126 may be configured to provide temporary access to locked videogame content, in response to the challenge criteria associated with the accepted challenge requiring videogame content not previously unlocked by the accepting player. The locked videogame content may include, without limitation, a venue, a vehicle, an aircraft, a watercraft, a pet, a weapon, a virtual opponent, a virtual teammate or ally, and/or other content.

(68) The challenge access module 126 may be configured to adjust an interface provided to the player during performance of the challenge. This may include providing a specialized interface that enables the player to track progress toward completing the challenge through performance of the task. By way of illustration, FIG. 13 shows a view 134 presented to the player that includes the videogame task associated with the challenge (in this case a car race). The view 134 may include visual elements 136 and 138. Visual elements 136 and 138 may correspond to challenge metrics associated with the challenge. Prior to achieving values for the challenge metrics that satisfy the challenge, visual elements 136 and 138 may include an icon indicating non-compliance with the challenge (e.g., the xs shown in FIG. 13). Referring to FIG. 14, upon achieving values for the challenge metrics that satisfy the challenge, visual elements 136 and 138 may be adjusted as shown to indicate compliance with the challenge (e.g., the check marks shown in FIG. 14).

(69) Returning to FIG. 1, as the player attempts the challenge, performance monitoring module 116 may monitor performance of the player. This may include determining values of performance metrics, as was described above with respect to performance monitoring module 28. The performance metrics include the challenge metrics of the challenge being attempted.

(70) The challenge monitoring module 128 may be configured to determine whether the player has achieved values for the challenge metrics that satisfy the challenge, and/or whether the player has completed the challenge. The challenge monitoring module 128 may make such determinations based on the values for the challenge metrics dictated by the challenge, and the values for the challenge metrics determined by performance monitoring module 116 as the player attempts the challenge.

(71) As the player completes the task associated with the challenge, the challenge monitoring module 128 may make a final determination as to whether or not the player has completed the challenge. This final determination may be the results of the challenge. Results of the challenge may be communicated to the player that issued the challenge (e.g., the player associated with first computing platform 12), other players that received the challenge, a specified group of players (e.g., friends of the player completing the challenge, friends of the player that issued the challenge, players that are friends of both the player completing the challenge and friends of the player that issued the challenge), and/or other players or groups of players. The results of the challenge may be communicated by challenge communication module 124.

(72) Responsive to the player completing the challenge, challenge creation module 118 may be configured to create a re-challenge for the task associated with the challenge. The re-challenge may include the same, or substantially the same, challenge criteria, or may include changes to the challenge criteria. For example, challenge parameters may remain the same, or may be incremented to a harder level (e.g., difficulty setting may be incremented up), or otherwise changed. The re-challenge may include new values for the challenge metrics, new or additional challenge metrics, and/or other alterations from the completed challenge. As will be appreciated from the following, the creation of the re-challenge, and possibly further re-challenges, may result in an ongoing interaction between players that transpires as the players asynchronously attempt to match or best each other's performance. The asynchronous nature of this interaction, and the basis of challenges and/or re-challenges on previous player performance may facilitate interactive participation in the videogame between players as the players attempt to one up each other, despite of circumstances that have previously inhibited interactive play. For example, differences in schedules, differences in equipment (e.g., different gaming platforms), and/or other circumstances may be overcome.

(73) A re-challenge may be created automatically by challenge creation module 118, or a re-challenge may be created based upon reception of user selection of a re-challenge. By way of illustration, FIG. 15 illustrates an interface 140 configured to receive selection, by the player that completed the challenge, of a re-challenge. The interface 140 may be presented to the player, for example through an electronic display similar to or the same as electronic display 106 (shown in FIG. 1 and described above). In creating the re-challenge, interface 140 and/or some other interface may be configured to receive user selection of the other players that should receive the re-challenge. This may include all of the players that received the original challenge and/or the player that created the original challenge, and/or other players.

(74) FIG. 16 illustrates an interface 142 configured to present a re-challenge 144 to the player that completed the challenge. The interface 142 may be presented to the player, for example through an electronic display similar to or the same as electronic display 106 (shown in FIG. 1 and described above). The re-challenge 144 may include one or more of a title 146, challenge parameters 148, a challenge metric list 150, content 152, and/or other components. The values for the challenge metrics in challenge metric list 150 may be the values achieved by the player in completing the original challenge. The challenge parameters 148 may correspond (e.g., be the same as and/or incremented from) the challenge parameters of the original challenge.

(75) One or more of the title 146, challenge parameters 148, challenge metric list 150, content 152, and/or other components of the re-challenge may be customized and/or configured by the player creating the re-challenge. The customization and/or configuration of one or more of title 146, challenge parameters 148, challenge metric list 150, content 152, and/or other components of the re-challenge may be accomplished in the same manner as the corresponding adjustment, customization, and/or configuration of a new challenge provided herein. For example, returning to FIG. 1, challenge criteria module 120 and/or challenge customization module 122 may operate in a manner that is similar to or the same as the operation of challenge customization module 34 and/or challenge communication module 36 in adjusting, customizing, and/or configuring a new challenge.

(76) The challenge communication module 124 may be configured to initiate transmission of the re-challenge to the appropriate other players. The re-challenge may prompt the receiving players to attempt the re-challenge, and/or may provide at least some of the challenge criteria for the re-challenge to the computing platforms associated with the receiving players. For example, challenge communication module 124 may initiate transmission of the re-challenge to first computing platform 12 for presentation to the player associated with first computing platform 12. The challenge communication module 124 may initiate transmission of the re-challenge in a manner that is similar to or the same as the manner transmission of the original challenge was initiated by challenge communication module 36.

(77) Upon receipt of the re-challenge at first computing platform 12, game module 24, performance monitoring module 28, challenge access module 38, and challenge monitoring module 40 may operate to present the re-challenge to the player associated with first computing platform 12. For example, game module 24, performance monitoring module 28, challenge access module 38, and challenge monitoring module 40 may operate in a manner similar to or the same as the operation of game module 112, performance monitoring module 116, challenge access module 126, and challenge monitoring module 128 in presenting the challenge to the player associated with second computing platform 14. The challenge communication module 36 may communicate results of attempts to complete the re-challenge similar to communication of results of attempts to complete the challenge by challenge communication module 124.

(78) Upon completion of the re-challenge by the player associated with first computing platform 12, first computing platform 12 may be configured to create a new re-challenge. The new re-challenge may then be provided back to second computing platform 14 and/or other players. Thus, the challenges and re-challenges may become an ongoing, iterative interaction between the player associated with first computing platform 12, the player associated with second computing platform 14, and/or other players.

(79) It will be appreciated that description of a player as being associated with a computing platform is not intended to limit the player's interaction with the videogame as described herein to a single computing platform. By virtue of a user profile that is portable between computing platforms (e.g., through portable storage media and/or networked platforms), a single player could participate as described herein through a plurality of different physical computing platforms. For example, user module 26 and/or user module 114 could provide for a single player to use a plurality of different computing platforms. Similarly, the issuance and attempts of challenges and re-challenges between a plurality of players may be accomplished through a single computing platform, as the players access the game through different user profiles.

(80) It will be appreciated that the illustration of first computing platform 12 and second computing platform 14 including completely separate sets of modules is not intended to be limited. In some implementations, some of the redundancy in the functionality provided by the modules of first computing platform 12 and the modules of second computing platform 14 may be reduced by providing some of the redundant functionality via a server in communication with one or both of first computing platform 12 and/or second computing platform 14.

(81) FIG. 17 illustrates a method 160 of enabling players to participate in competitive challenges within a videogame. The operations of method 160 presented below are intended to be illustrative. In some embodiments, method 160 may be accomplished with one or more additional operations not described, and/or without one or more of the operations discussed. Additionally, the order in which the operations of method 160 are illustrated in FIG. 17 and described below is not intended to be limiting.

(82) In some embodiments, method 160 may be implemented in one or more processing devices (e.g., a digital processor, an analog processor, a digital circuit designed to process information, an analog circuit designed to process information, a state machine, and/or other mechanisms for electronically processing information). The one or more processing devices may include one or more devices executing some or all of the operations of method 160 in response to instructions stored electronically on an electronic storage medium. The one or more processing devices may include one or more devices configured through hardware, firmware, and/or software to be specifically designed for execution of one or more of the operations of method 160.

(83) At an operation 162, performance of a task within the videogame by the first player may be monitored. The performance of the task may be monitored with respect to one or more performance metrics. In some implementations, operation 162 may be performed by a performance monitoring module similar to or the same as performance monitoring module 28 and/or performance monitoring module 116 (shown in FIG. 1 and described above).

(84) At an operation 164, a challenge may be created based on performance of the task by the first player. The challenge may be created such that to complete the challenge the task must be performed while at least equaling the performance of the first player with respect to at least one of the monitored performance metrics. Creation of the challenge may include customizing the challenge and/or selecting which performance metrics should be used to determine completion of the challenge. Creation of the challenge may include determining one or more other users, such as a second player, to whom the challenge should be presented. In some implementations, performance of operation 164 may be performed by a challenge creation module, a challenge criteria module, and/or a challenge customization module similar to or the same as challenge creation module 30, challenge criteria module 32, and/or challenge customization module 34, and/or challenge creation module 118, challenge criteria module 120, and/or challenge customization module 122 (shown in FIG. 1 and described above).

(85) At an operation 166, transmission of the created challenge may be initiated to the appropriate player(s). For example, transmission of the created challenge to the second player may be initiated. The challenge may be transmitted in the form of a challenge invitation. In some implementations, operation 166 may be performed by a challenge communication module similar to or the same as challenge access module 38 and/or challenge communication module 124 (shown in FIG. 1 and described above).

(86) At an operation 168, the challenge (and/or corresponding challenge invitation) may be received by the second user (and/or a computing platform associated therewith). In some implementations, operation 168 may be performed by a challenge communication module similar to or the same as challenge access module 38 and/or challenge communication module 124 (shown in FIG. 1 and described above).

(87) At an operation 170, access to the received challenge may be provided to the second player, in response to receiving acceptance from the second player of the received challenge. Providing access to the challenge for the second player may include enabling the second player to attempt the task associated with the challenge in the videogame. In some implementations, operation 170 may be performed by a challenge access module similar to or the same as challenge access module 38 and/or challenge access module 126 (shown in FIG. 1 and described above).

(88) At an operation 172, performance of the task by the second player may be monitored. The performance of the second player may be monitored with respect to the one or more performance metrics associated with the challenge. Monitoring the performance of the second player may include determining a result of the attempt to complete the challenge. In some implementations, operation 172 may be performed by a challenge monitoring module similar to or the same as challenge monitoring module 40 and/or challenge monitoring module 128 (shown in FIG. 1 and described above).

(89) At an operation 174, transmission of the result of the attempt of the second player to complete the challenge may be initiated. The transmission initiated may include transmission to the first player, other players that received the challenge, and/or other players or groups of players. In some implementations, operation 174 may be performed by a challenge communication module similar to or the same as challenge access module 38 and/or challenge communication module 124 (shown in FIG. 1 and described above).

(90) At an operation 176, responsive to completion of the challenge by the second player, a re-challenge may be created. To complete the re-challenge the task must be performed while at least equaling the performance of the second player with respect to the performance metric(s) associated with the challenge. In some implementations, operation 176 may be performed by a challenge creation module, a challenge criteria module, and/or a challenge customization module similar to or the same as challenge creation module 30, challenge criteria module 32, and/or challenge customization module 34, and/or challenge creation module 118, challenge criteria module 120, and/or challenge customization module 122 (shown in FIG. 1 and described above).

(91) Upon creation of the re-challenge at operation 176, method 160 may return to operations 166, 168, 170, 172, and 174, where the re-challenge may be processed in a manner similar to or the same as the processing of the challenge described above.

(92) Although the invention has been described in detail for the purpose of illustration based on what is currently considered to be the most practical and preferred embodiments, it is to be understood that such detail is solely for that purpose and that the invention is not limited to the disclosed embodiments, but, on the contrary, is intended to cover modifications and equivalent arrangements that are within the spirit and scope of the appended claims. For example, it is to be understood that the present invention contemplates that, to the extent possible, one or more features of any embodiment can be combined with one or more features of any other embodiment.
