Don't bother with Vampire Savior, they changed too much over Nightwarriors. So yeah, Darkstalkers for Saturn (Nightwarriors) is an amazing game. I bought it the day it came out long ago, and sold it when I sold my Saturn five years ago, and regret selling both to this day. For those who ask about the difference between Saturn and PS1 fitghters, nearly all Saturn fighters were arcade perfect or at least closer than PS1. PS1 fighters almost always lacked animation. And Duo, without a doubt the Saturn pad is the single best pad for fighters ever (though the Japanese one topped the US one)
