I play guitar, and have played guitar hero and it's actually kinda fun. It teaches rhythm at least, which is something most bedroom guitarists lack.

I also play drums/bass & sing, and I'd have to say that the mic and drums of rock band are the ones that are closest to the real thing, which is probably why people who can't sing or play drums have trouble with em'.

What these guys did is kinda cool fer sure. But it's just a novelty & my practical side questions the merits of learning an instrument that's so limited in so many ways relative to a real guitar. They got themselves a cool shtick tho so wutevah
