Street Fighter IV for Windows ships today in North America, and should be hitting stores now. And for those looking to kick some ass without getting off of theirs, the game is also available via digital distribution from Direct2Drive, Impulse, and Steam. The first rule of fight club is you don't talk about fight club, but fortunately, this isn't fight club, so here's word on Capcom's fighting game sequel: "Street Fighter IV brings the legendary fighting series back to its roots by taking the beloved fighting moves and techniques of the original Street Fighter® II, and infusing them with Capcom's latest advancements in next generation technology to create a truly extraordinary experience that will re-introduce the world to the time-honored art of virtual martial arts."
