We're still enjoying Guitar Hero at my office but I would be willing to move the Wii to a more spacious location in order to accomodate this awesome new Ion Audio drumset for Rock Band.
Contrary to popular belief, San Francisco is not a great music town, at least not if you are a drummer and want to practice in your house. Unlike the east coast (and presumably elsewhere) where basements are plentiful, the bay area is lacking in-home practice areas.
Generally speaking electronic drums are not that satisfying, but bring some video games into the mix and I'm on board. During a trip to Japan I sat down at the full-size drum machine game and played along to Crazy Train. All the kids thought I ruled until I told them I actually knew how to play.
