Play Dirty 2

A game master advice book focused on adversarial techniques for tabletop roleplaying. It presents traps, twists, complications, and other deliberately villainous methods for challenging player characters, including long-term consequences, social opposition, and extreme threats. The material is intended to create memorable setbacks and encourage players to hate the game master's schemes while engaging with the story.
