Rule Zero says the Game Master can overrule the rules. But if the rules don’t matter, why have them at all? This episode examines this paradox at the core of tabletop gaming: the balance between written systems and the GM’s authority. We explore the idea Rule Zero from its role as a safety valve for incomplete designs to its modern use as a philosophy of play. Along the way, we explore how it protects creativity, enables bias, and tests the very idea of what makes a game fair or meaningful.
