A non-transitory computer readable recording medium having recorded therein a program executed by a processor of a server apparatus, the program causing the processor to: receive a first user's input for a competitive video game that uses (i) card objects of the first user of a first terminal apparatus, and (ii) enemy card objects of a second user of a second terminal apparatus; place, on a first deck zone, a first type card object of the first user, place, on a second deck zone, a second type card object and a third type card object; in response to a first user's input; allow the first type card object to be placed on a first area on which placement of the enemy card objects is not allowed; allow the second type card object placed on the second deck zone to be placed on a second area on which placement of at least one of the enemy card objects is allowed; and allow the third type object card placed on the second deck zone to be placed on the first area or the second area.

A computer system controls a start of a gathering event that gathers a user character of a participating user at a given gathering place in a virtual space upon acceptance of a gathering request operation from a terminal of a directing user. The computer system controls a display of a map image displaying the gathering place in the virtual space in an identifiable display mode on the terminals of the directing user and the participating user. The computer system determines a success/failure of the gathering event using a position of the user character operated by the participating user. The computer system gives a given reward to the directing user and/or the participating user when the gathering event is determined to be a success in the event success/failure determination.
