Well, I'll join in for everything except World Tour which I will never touch again even if my life depends on it.
So I'll participate in all GH2 and GH3 stuff on Xbox360. I play expert and am pretty good, 5 starred everything in both games except TtFaF which I 4 starred though...
PS: How about Rock Band & Rock Band 2 also? They are the better games, honestly.
