I'm more of a guitar hero fan personally, not the orginal games, the sequels like the metallica version was pretty nice. I did have rock band 2 though, and I loved the whole fans thing where the better you played the more fans you picked up, really enjoyed that. If you have GH though i'll give you a go at that . Whats your psn?
I used to play a lot of GH before I picked up RB actually, but I just like RB a lot more. And the fans system is the same in RB3 and you can get some pretty damn cool things from it. For example I always play on a huge stage now instead of just a small podium.
My PSNs are I think Mugetsu_96 and Shikamaru_96 (if the first one doesn't work then try it without the underscore). I forgot which is my English and which is my Japanese, so just add them both to be sure.
I could dig up GH again but I don't have any GH games for the PS3 and I'm not really planning to get any. I don't like the setlists that much for as far as I know them.
