There was a rockband demo set up at Wal*Mart (garden center). There was actually all 3 systems set up. Mario Galaxy on Wii, Scene it on 360, and Rock Band on PS3 (Guitar and Drums). I played Rock Band. Was fun. I got a 89% on Wanted Dead or Alive.
The thing I laugh at is that the demo will make it so that it seems that Rock band is only available on the PS3.
Still its a fun game.
