That same kid like...aced Freebird on GH2 I think, its unreal. I can barely pass Hard at times, I don't know how this kid does it. Oh, and I don't think I can do that DragonForce song hes playing...on Medium.
Beaten GH3 on Medium, working on Hard difficulty in Co-op mode. The set list is nice, Knights of Cydonia and One are a bitch to play. One lures you in, thinking its not gonna be bad...then you remember its Metallica and it'll kick your butt halfway through.
Played Rockband last night, buddy picked it up without the instruments. We just played with Guitar Hero guitars, it was still pretty cool. I like the look of the crowd, I'm not so sure the hammer-ons and pull-offs work as well as GH3 though, I think I got gipped a bit. I think Hard difficulty is better tuned on Rockband than GH. On GH it seems the jump from Easy to Medium isn't bad, but Medium to Hard is much more difficult to overcome. We were able to play Hard on Rockband without getting our butts handed to us as bad, I probably did 5-10% better on Rockband's Hard difficulty compared to GH. Just an observation so far, I was playing Bass half the time though.
