blarg, SF3 is about as overrated as a 2d fighting game can get. I've seen good players in person (like Justin Wong) and I still can't see why people still play it seriously. The game is about Ken, Yun, and Chun and the wonders of standing across the screen whiffing attacks until they gain a super.
Not really a big SFA3 fan either, but I don't really have anything personal against it, I just don't like any custom combo based games.
