Whoa, wish I seen this sooner.
People still think Smash Bros. is a fighter? So do they consider Playstation All-Stars a fighter too?
Anyway, besides puzzle games, fighting games are my favorite genre. I'm more inclined to Arc System works fighters(Guilty Gear, Blazblue, Persona 4 Arena) though. There are also a few doujin fighters I like, like Eternal Fighter Zero, Aktsuki Blitzkampf and Melty Blood.
