Fei Long vs Marshall or Forest Law! A battle on which is the best Bruce Lee imitator!
I'd be interested to see how Tekken x Street Fighter will work out, especially for the Street Fighter characters since projectiles don't exactly work too well, or just aren't common enough in 3D-pane fighting games, apart from maybe ridiculous special or boss characters.
Maybe this will be a chance to see Street Fighter characters portrayed and adapted in a more realistic 3D fighter approach. For example, Hadoken's could become some close range palm attack, Tatsumaki Senpukyaku's would be a double jump spin kick (Without the flying) or something.
3rd Strike Online Edition is a great addition, although lag might pose some problems with the parrying. Either way, it is about time though. I hope one day we could see Alpha 3 get the same treatment.
