As game masters we wear many hats, and there are a lot of skillsets involved. Today I discuss the GM as rules arbiter. When it comes to the rules of an RPG, the buck stops at the GM. Most RPGs have a rule zero which gives the GM ultimate authority when it comes to the rules, not the books or developers of the game. Second, I will begin a series of segments in which I will dig into the PHB and DMG. If you’ve been asking for episodes on how to play and/or run RPGs, this is for you! Hopefully I’ll tease out some gems from these books you didn’t even know were there.
