Hands down street fighter 3 is one of my top fighting games. I love it so much. I got into sf4 a bit after downloading it, still prefer third strike. I think I've been enjoying kof 13 really brought the series back for me. Tekken was a big part of why I got a ps3. Soul calibur was fun but the none of the ps2 games had the same magic as the dreamcast original, they didn't blow me away.
The two fighting games I like are soul cailbur and blazbue. I enjoy soul clailbur series because of the weapon based combat and depth. As for blazblue, I like anime and the story mode is pretty good for a fighting at least.
