Do the drums for this game with with RB/GH? If so, that's pretty good. Cuz even though I hear the game is garbage, it has a TIV of $19 at BBV. So $11 for a drum set is nice.
I got the rock revolution drums bundle for $20 at Hasting a couple weeks ago. The drums work with GH: World Tour, haven't tried them out with RB 1 or 2 yet, but I would assume they will work as well.
