I think my least favorite thing in fighting games is when they lock you into the main character for the single player mode. It's especially bad in this era, because wow they sure did love their bland karate guys.

"Hey game, can I play as the cool looking pirate dude or the girl?"
"No, you're gonna play as your dull-ass karate guy and you're gonna like it."

Bonus star for having Toguro as the final boss, that's pretty neat.
