I've played the hell out of Guitar Hero, as well as Rock Band (a very similar game). The Guitar Hero franchise recently was discontinued by Activision. Rock Band, in its latest version, added a keyboard controller, as well as a real guitar controller with 6 strings and 21 (or 22) frets. I happen to be on the Wii, but if you are on the XBox, there is a Rock Band thread in this same forum section where you might be able to hook up with some folks, as many folks own both. Many instruments work on both games, as the folks who made Guitar Hero split off to make Rock Band.
