I don't know whether it's still planned to release this for the PS3, or whether it's been scrapped in favour of Guitar Hero 4: World Tour, but I'll tell you this: the game kicks ass. I've played it at the Omega Sektor, and it's absolutly amazing as an experience. Just grabbing a couple friends and smacking out a few songs like that. I was the singer, obviously, owing to the fact that I came second in a recent Guitar Hero competition to my friend, who was also in attendance, and thus took up the guitar. Some random guy was on drums, but he was cool. He had an afro. And it's just such a fun experience to do. The three of you working together, trying to produce an awesome performance. Of course, it takes up to 4 people, but the only other guitar in the place was hooked up to Guitar Hero 3. But simply as an experience, a way to kick back with friends and relax, it's a completly awesome game. The technology is amazing, all of you work together during gameplay (with failed musicians having the possiblilty to be brought back by their successful partners) and it's just so much fun to play. It's got songs for everybody, with songs for my kind of taste (When You Were Young by The Killers, Should I Stay or Should I Go by The Clash, Dani California by RHCP and of course, Enter Sandman) all the way up to some random bloody foreign song. I didn't do that one. I'll be damned if I'm gonna try singing in Norweigan.
Oh, and also, to Monkey: at one point, I did the Guitar and singing at the same time. I kicked When You Were Young's ass. My tip is that it's easy enough to do, as long as you pick a song that you know the lyrics to.
