So, I got the Rock Band Stage Kit in for review. You know, the fog machine / strobe light / LED lighting effect kit that says, "Hey, I take Rock Band waaay too seriously."
Well, you can see my review of the Rock Band Stage Kit at GameVortex.com, but in summary, I'll just say that it really does change the feel from simply playing a game to much more of a performance. This is just the desired effect for parties that I go to, so I'll have to tote it along.
I tried it out at a "Gaming Day" at work, with Rock Band 2 (Xbox 360), Guitar Hero World Tour (PS3) and some various Wii games and it was a big hit. The gaming session lasted from 4:PM to 8:PM and, at the end of the day, we were down to five people rotating in and out of a Rock Band 2 game, with the Stage Kit going... well, without the fog, since you can't lower the amount of fog to reasonable amounts... and we wanted to actually see the screen.
