Often times game masters (GM) spend as much time preparing for games as they do running them. Every GM has their own methods which are usually developed through trial and error because quite frankly, for everything written about game mastering there is very little said about the process of "session prep." The lucky GMs have someone to guide them but the unlucky ones are forced to stumble through until they eventually figure things out for themselves.
Never Unprepared shows GMs how to skip the grueling task of learning game prep. Based on decades of experience this book helps GMs boil down session prep to a simple but thorough process with allows for focus on what is most important to the game. Then it shows you how to schedule those tasks so your session prep can go as smoothly as possible.
This book is written independent of system so GMs will find it useful for any game. I have been a GM for over two decades and I found this book had plenty of suggestions to make my session prep even easier.
