Displayed on a first LCD 11 are a “fire” planet 40a, a “wood” planet 40b; an “earth” planet 40c, a “wind” planet 40d and a “water” planet 40e, each traveling along an orbit by a unique orbital period. While an attribute symbol is traveling through an active zone that is associated with the attribute symbol, the status of the attribute represented by the attribute symbol is active. An attribute being active affects the space attribute, which is the attribute of a particular space in the game world. The space attribute affects the ability parameters of characters of the same attribute. Thus, it is possible to enrich the strategic aspect of a video game using characters' attributes.
