So you are addicted to guitar? Wanna play guitar games wherever you go? I would recommend a game called tap-tap for ipods. Simply search it in the search engine, and you should be able to find it. Apart from that guitar game, you could also try guitarway to heaven, a psp homebrew game. Of course, the king of all guitar games, without a doubt, goes to guitar hero. But if you are looking for free guitar games, the others are your best choice.
