Oh, this'll be good.
Sir Walter Beck (Fable 3) "before we go any further, I'd like to say one thing..."
Orange castle crasher (Castle Crashers)-- What could possibly go wrong?
Balthier (Final Fantasy XII)-- Poker with a Sky Pirate? Of Course!
Asura (Dungeon Fighter Online)-- I'd play poker with a blind guy.
Well, I'd imagine Walter being relatively good at poker (or Feeble. He can't possibly say no to Feeble!), the orange castle crasher will attempt to set everything on fire/steal the princess from the other players, and the Asura could see everybody else's hands ("using his minds eye" or something like that).
But, in the end, Balthier would win. He is the leading man, of course.
