Operation data is acquired from either a first type of controller having a plurality of operation sections or a second type of controller having fewer operation sections, and a game process is performed. When the first type of controller is used for game operation, a selection item is switched in a forward direction for a plurality of items arranged in a predetermined order, in accordance with an operation on a first operation section, and the selection item is switched in a reverse direction in accordance with an operation on a second operation section. In addition, when the second type of controller is used for game operation, the selection item is switched in the forward direction in accordance with an operation on a third operation section of the second type of controller. Then, a UI image including these items is generated.

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.
