episode 70: GMJ 070: GM 101: Session Zero, House Rules, Worldbuilding & Thinking on Your Feet
Today I set off again on the Obsidian Monolith to answer the question, “How do I become a game master?” In the second of my series of GM 101 episodes, I respond to your feedback and do my best to answer your questions about game mastering. I discuss session zero, speeding up and slowing down combats, when to house rule (and when not to), worldbuilding and thinking on your feet.
