Super Street Fighter II
Soul Calibur II
The Last Blade II
Probably Super Street Fighter IV, but I haven't played enough with it.
GC version of SC2 I loved. Smoother framerate than the PS2 and it had Link which was more interesting than Heihachi. Spawn was kool, but I didn't like how he was implemented.
SSF2 I find a great game. Best SF game to date imo.
Playstation = The Beast from the East
Sony + Nintendo = WIN! PS3 + PSV + PS4 + Wii U + 3DS
