I've played Guitar Hero at a party (on a playstation dedicated to playing, with dedicated instruments), and liked the experience. (Although I never liked computer games before.)
So, I'd like to find a similar game for my GNU/linux system. It should:
- be controlled with the normal keyboard/mouse,
- desirably, be free software (= open source), so that all people around the world can hack it,
- allow adapting well-known popular music compositions for playing in it. (I'd like to find a collection of adapted songs that would include more songs that I like.)
So, what are the analogues of "Guitar Hero" for GNU/Linux that are there?
