A parameter of a consumption item (fuel, life) consumed as a game progresses is calculated. When a setting of a game termination condition changes, a rate of change of the parameter of the consumption item is changed according to the change of the setting. The game termination condition is a condition relating to the number of laps on a course, a time limit of a game or a game quota. The rate of change of the parameter of the consumption item is increased as the number of laps on a course is reduced, as the time limit of a game is shortened, or as the game quota is reduced. When a value of the parameter of the consumption item becomes equal to zero as a game progresses, the movement or motion of an object is disabled. The parameter of the consumption item is changed from an initial value set by a player with the rate of change which has been specified based on the game termination condition set by the player.
