A controller of a game apparatus causes a display unit of a player to display a first game screen on which commencement of a battle event can be instructed. When the player instructs the commencement of the battle event on the first game screen, if the player has a collection-not-completed item group in which only some items have been collected among a plurality of items, the controller causes the display unit to display, immediately after the first game screen, a second game screen on which another player who owns an item not yet collected by the player in the collection-not-completed item group can be selected as a candidate from whom the item is to be taken when the battle event is achieved. |
