"We weren't able to get any time playing online in time for the large Street Fighter IV review, but now that the retail version of the game is in my office, I can hook up my arcade stick and see just how well this fighter does online. Does the system work, or are you better off just playing local games?
The first thing to remember is that you should turn off the feature that allows others to challenge you while in Arcade mode. If you're trying to unlock characters or just practice, it can be a pain in the butt to be yanked out of your game simply because you came up on someone's match-making radar. In your network settings, set "Arcade Fight Request" to "Request: Off" and you won't be interrupted. If you're always spoiling for a fight, keep it on."
