The graphics look worse than when running on the Saturn in many respects, and the music stutters a lot. If you can stand that then you can emulate the game.
Personally, I played SF3 for the complete experience, meaning both the gameplay and journey. Gameplay-wise SF2 is better IMO. SF2's higher difficulty settings give it a lot of replayability. I just wish that someone could translate that gameplay into 3D properly.
Now we could wait a decade for someone to perfect Saturn emulation. I'm sure it will happen... eventually.
Either way, we have better games to play. I still need to complete VC. That game really is a work of art if you enjoy the gameplay (of course, I prefer medieval fantasy for a number of reasons).
This series isn't financially viable I imagine. I wish that Camelot had made SF3 for the Dreamcast instead. It would have been vastly superior in every way imaginable (not to mention compatible with PC software).
