Abstract: A game system moves a player character in a virtual game space in accordance with an operation by a player. Further, the player character's moving amount per predetermined unit time is detected at each predetermined time interval. A predetermined parameter (gage amount) value is calculated at each predetermined time interval based on the moving amount detected at each predetermined time interval. Also, the game system adds the predetermined parameter value calculated at each predetermined time interval for accumulation. In response to a predetermined operation performed by the player, the game system causes the player character to perform a predetermined motion (e.g., special shot) on a condition such that a value obtained as a result of the addition reaches a predetermined value.
