I picked up SF4 Collector's Edition today for the 360!
So far I'm liking it and all it's features.
Though, I have one issue with the game, or rather the controller itself. The 360 controller doesn't play well at all with the game's charge and multi backward forward/up and down attacks at all. The thumbstick over does quick movement with the thumbstick and there's no control in doing such a move. Andusing the d pad just feels clumsy with the game.
All in all, In short, I'll prolly have to get an arcade stick if I have any hopes of doing Chun Li's Ultra combo. Oh, The pain of transfering an arcade game to the home consoles.
Though, Ryu's I can do with ease. Fluid motion moves are pretty easy to pull off. :P
