Seconded! Remember Guitar Hero 2 is coming out very soon.

It ain't a first person shoot em up or a driving game (which are my two favourite genres) but I think GH is the best game of all time... partly for the reason that it can be played by EVERYBODY (caveat..arms, hands and fingers are necessary)

Trying to persuade my brother to buy it too - so we can play head to head. And I'm really going to try to get one of my songs on GH3!
