The one thing every Game Master needs in order to run a session for their friends is an adventure. This book gives them everything they need and then some. Good, professional-quality adventures are a necessity to play the game, but they can be expensive, sometimes costing upwards of $50 or more. Writing your own adventures can be a lot of fun, but it takes an enormous amount of time to do so. The Game Master's Book of Adventures on Demand solves these issues by providing GMs with nearly a dozen adventures, each suitable for an evening or two of play. They can be run as standalone game sessions or they can be linked together into one long, ongoing campaign using a unique "Facilitator" that provides a connective tissue between adventures as well as epic climax against a one-of-a-kind, earth-shaking villain. And as with every book in the Game Master series, this volume is packed with dozens of extra tools designed to help GMs run their sessions with less stress and more fun. In addition to the ten one-shots and the Facilitator, Adventures on Demand also provides instructions and tables for bringing adventuring parties together in fun and unique ways, adding complications and twists to existing or home-brewed adventures and enhancing adventures with unique add-ons that elevate the playing experience. GMs will also find information about constructing different types of adventures from scratch or skinning existing adventures to fit the GMs preferred genre or style of play.
