Soul Calibur (didn't like 2 as much)
Tekken 3
Samurai Showdown
Last Blade
Garou: Mark of the Wolf
Bushido Blade

Fighting games used to be my specialty, I could school anybody back in the 16-bit era. Then when the PS came out, I didn't get one until about the third year of release, and my N64 had maybe two decent fighters on it, so everyone else got ahead of me again. :|

My old-timey 16-bit favorites were SSF2, MK2, and KI. My more recent pics are Marvel vs. Capcom 2, Soul Calibur, DOA3, Guilty Gear X2, and SFA3.

i'd have to say that SC2 kinda tops my list, but there are so many other fighting games that i love, all the capcom stuff, most snk, Samurai Showdown, bushido blade (one of the first games that you could actually mutilate your opponents, aka, chop off their arms and stuff)

edit : Killer Instinct ties for first place with Soul Calibur 2......
