I've only played what's on the Neo Geo Anthology, Virtua Fighter 4 (I think that's the number) and all the MKs. I've enjoyed them all. I also have that last Art of Fighting game, but haven't yet opened it.
My favorite is Hokuto no Ken (Fist of the North Star) from Arc System Works (Guilty Gear series) and Sega. The fighting engine is so broken, but it's still very fun to play. Check it out: http://www.youtube.com/watch?v=gVeKN...feature=colike
I don't own that many fighting games on the PS2, tbh, the only ones I have are DBZ ones. Super DBZ is a good fighter, tho, so that.
