A program executed in a game device causes a controller to move a plurality of operated characters in a virtual three-dimensional space in accordance with operation signals; decide a moving direction of a field-of-view range; set a screen end of a display screen of a game image on the opposite side of the moving direction of the field-of-view range; generate, if a first operated character is located at a predetermined point outside the screen end, an operation event for receiving a specific operation from an operation unit operating the first operated character; and move, if the specific operation is received when the operation event is generated, at least a second operated character in the plurality of operated characters toward a position of the first operated character. The second operated character is closest to a screen end of the game image in the moving direction of the field-of-view range.
