I'm just this guy, you know? A thirty-something and probably the quintessential Sino-American geekster, with the only significant difference being I live nine hours ahead of Los Angeles.
My preferred game genres are music/rhythm games and the occasional FPS/action RPG (Bethsoft RPGs, Mass Effect, etc.). Rock Band 3 and variants of Rock Band probably inhabit 90+% of my gaming time, with the rest mostly devoted to things like the latest Bethsoft release or whatever game du jour happens to be out there. Before Rock Band, there was Guitar Hero and DDR. Less so nowadays, although I'm still happy to play HVAM on singles expert since apparently I don't quite have the muster for HVAM doubles anymore.
I currently don't buy Activision games because I don't like the publisher, even if I like the games or developers. I actually enjoyed what I've played of Guitar Hero 5 and DJ Hero, but I'm adamant about not purchasing their games. Possibly used. Maybe next time I'm in the States, I'll go to a GameStop or something, I dunno.
