Not in particular, I just know this junk because I used to be a MASTAH with Samurai Shodown. Kuroko is the referee guy, and is a playable character in two of the games. Truth be told, i study whatever interests me at the moment. Quantum physics, game theory, microprocessors, biofeedback, cookie recipes, you name it. Google is an excellent professor.
EDIT: ARGH! I have to wait a whole minute to edit ONE LETTER?
