From the book introduction: Disaster!™ is a simple-to-learn roleplaying game where players take on the roles of victims and heroes in a cheesy catastrophe movie. It assumes the players and ref already have some rudimentary experience with roleplaying. It is meant to be played in the vein of movies like Airport ‘77, The Poseidon Adventure, Tornado! and Earthquake. Make the bad puns fly, keep it light, and pass the popcorn.
