I'm here to let everyone know (if you don't already) that Rock Band is quite possibly the best game ever created (next to Final Fantasy VII of coourse).
Don't get me wrong, I give all the props in the world to Guitar Hero for kicking off the phenom but Rock Band jumped way ahead when they released. I have played the PS3, PS2, and 360 versions(not Wii). PS3 is the clear winner. Just stellar. XBOX wasn't wireless (guitar) and the playability was lacking. Even on a standard TV the instruments just didn't respond like on the PS3. The PS2 version is just to limited. You cant do most of the things on PS2 as you can on PS3. Rock Band 2 is already out on 360 and will be out Oct 19th on PS3. Can't wait. Guitar Hero is also releasing a Rock Band like game called World Tour. It will have all the instruments that Rock band has. The other bonus is that PS3 is trying to make all of the instruments for both games interchangable between the games. I'm sure I will pick up both. The Guitar Hero release date is around the same time as Rock Band 2.
Bought RB 2 on the 19th. Love it! Some of the songs are a little iffy but thats life. When you register the game online they offer you vouchers for 20 more dowloadable songs to be released at a future date. Also downloaded the BloodSugarSexMagic album and Dr. Feelgood.
