Actually, there are rules. Quite a few, but no God Mode bullcrap, so there has to be a limit to your abilities and you have to have weaknesses. Also, no character jacking, so making other players decisions for them when they're duelling. Like: "You turn your back for some apparent reason, allowing me to stab you in the kidney 16 times." None of that shit. Mmk? Edit: Also, when Ninja said "no rules" in the op, he was referring to the ranking system before this shit happened.
