I can't wait to get my hands on Guitar Hero II, I think it'll be a great game to play, not because I'm a hardcore rock enthusiast, but because the game itself is fun to play. I've tried the first game, and it got my eyes up for some pretty good bands, that I didn't really know of. And the rock is the genre I prefer. It's also a worthy challenge for any gamer and you'll eventually learn to twist your fingers in ways not meant to be.
So if you're bored and you desperately need something to spend your money on, I think I can recommend the Guitar Hero franchise
Unless you hate games and music.
