"Guitar Hero"'s main mode of play is Career Mode, where the player and in-game band travel between various fictional performance arenas and perform sets of four or five songs. Completing songs in this mode unlocks the songs for play within the other game modes. Players can choose their on-stage character and their guitar; these elements have no effect on gameplay but affect the visuals during the performance. In Career Mode, players can earn money from their performances that is redeemable at the in-game store, where bonus content, such as additional songs, guitars and finishes, can be unlocked. Quick Play mode allows players to play any unlocked track, selecting the difficulty, the character, venue and guitar. After successfully completing a song in either Career or Quick Play mode, players are given a score and a rating from three to five stars, depending on their overall performance.
