Abstract: 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.

Abstract: An advertisement that has been watched by a friend but has not been watched by a target player is controlled to be displayed at a timing satisfying a timing condition defining a timing at which the advertisement is displayed, in a game played by the target player. At that time, information indicating that the advertisement has been watched by the friend is also controlled to be displayed. A reward for watching the advertisement is given to the target player. The reward changes in accordance with the number of the friends who have watched the advertisement and a friendship level of the friend. The target player is further notified that the advertisement has been watched by the friend, and thus the reward has changed.

Abstract: When a player sets an acquisition target item to be an item he or she wants at a timing of creating a plan, actually required points that are required for acquiring the acquisition target item is determined. Then, options of the advertisement plan in which one or a plurality of advertisements are listed so that watching points reaching the actually required points can be acquired, from options of advertisements that can be watched in exchange for the watching points. When any of the plans is selected and confirmed, an advertisement is displayed based on the plan, and the watching points are given to the player. When the sum of the watching points given reaches the actually required points, the acquisition target item in the plan is given to the player.
