A game system is composed of a TV, a hand-held game machine, and a game apparatus, for example. A hand-held game machine and a plurality of controllers are connected to the game apparatus, for example. The hand-held game machine displays a first game screen which indicates the positions of first to fourth characters in a game space. The TV displays second game screens which respectively correspond to second to fourth characters, each of the second game screens displaying only a limited extent of the game space. When a predetermined condition is satisfied, an operable character for a player is switched from a first character to a second character. Since different extents of game space are displayed for different characters, an interesting game can be provided.
