Hello how may I help you? Hi, I have a question about the rules of a game. That's what I'm here for! What game do you need help with? If I'm the Dungeon Master in a D&D game, can I make a rule that nobody can play a dwarf. If you're the Dungeon Master, you make the rules. Any rules you want. Really? If I wanted to, could I make everyone play as cats? You're the Dungeon Master. Meow! Can I break into their houses and replace their dice with ones that only roll low numbers? I'm afraid that may be considered illegal activity. I'm not equipped to help you with those kinds of rules though. Oh, OK. I guess I could just have them fail even if they roll high numbers. That's not illegal, is it? As far as I know, that's all part of the game! Thanks, you've been very helpful!
