Abstract: The present invention can provide a game system and the like that improves the interest of the game in playing a plurality of people by adjusting difficulty of a game with maintaining game enjoyment based on the timing of operation inputs, and providing the production for livening up a battle performed by a plurality of players. The game system S of the present embodiment performs an evaluation process of an evaluation for each player based on an operation input timing and a given relationship between a mark object for determining operation input timing and an operation timing object; moves, in a second direction that is a direction opposite to the first direction, the corresponding operating-system object formation area in accordance with the evaluation of the evaluation process; and set at least a part of the operating-system object formation area to the non-display range.

Abstract: A game system accepts a position designation operation performed for an operation area OA as a first input operation, and performs game calculations. In this game system, a disturbance area DA is set in the operation area OA when a given disturbance condition has been satisfied. A position designation operation performed for the disturbance area DA is not accepted as a first input operation. The disturbance area DA is canceled when a given cancellation condition has been satisfied.
