I'm keeping it broad for now. Is anyone out there really into rhythm games? Everyone has tried DDR or Rock Band, but I'm curious if anyone on the board seriously plays them. Not serious in an "I'm going to crush everyone" mindset, just that you've put some effort into getting better at it.
I play a lot of Rock Band, tend to download whatever DLC strikes my fancy (and meshes well with my musical taste, which is ample), do a lot of vocal + instrument. I love playing in public, and get to do so weekly at a local Rock Band night (though I still have to hear "Don't Stop Believin'" almost every week). Always looking for more people to play it with, preferably if you play on expert. I tend to score-whore.
I dabble in DDR as well (dabble is being modest, I've been playing for a while). A local arcade has a Supernova 2 cabinet, and I swing by there every other week or so. Not a big scene in my area, so it gets kind of lonely. I know other people play it, they're just rarely there when I am.
