A downloadable video game clone of Guitar Hero. However, Neversoft decided it was too much like Guitar Hero, and sued it's ass. Despite Neversoft really not being allowed to sue them for anything, because some Japanese company owns the rights to rhythm video games that have guitars in them, Guitar Zero took down their website to go and make the game "Less Guitar Hero-ey".
