Abstract: A computer system performs progress control of a game where a first team and a second team fight with each other in a game space including settings of a first team headquarters, a second team headquarters, and at least one intermediate base that either of the teams can alternately capture to use as a base. A game screen includes display of headquarters gauges whose gauge values increase or decrease in accordance with headquarters parameter values indicating conquered degrees of the first team headquarters and the second team headquarters. Capture difficulty of the intermediate base is adjusted based on the gauge values of the respective headquarters gauges of the first team and the second team.

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.
