Story Mode- Utterly useless.
Quick Battle- Decent replacement for Edge master mode, Better than IV's Tower or that RTS hybrid in III
Arcade Mode- Interesting structure if you've played Fighters megamix it's a familiar set up.
Graphics are amazing, Music is great, Stages are alot better than the ones in IV
ZWEI is my new favorite
Ezio is awesome.
Creation mode is the only thing that really needs work. I was still able to create myself and the 4 other Retrocade Characters (Dr Levesque, Fred Hebert, Smitty and Cheza) But it really lack variety at this point. Maybe I need to unlock items or something. It would be nice if you could create a character using Ezio's Style but so far you can't.
But so Far it's a huge step up from III and IV. It's Basically what III and IV should have been.
