I love this book. Presentation is excellent. It could have come right of the shelf of a bookstore. The game itself is fantastic. The advice for running a sandbox game is outstanding. You could have very little (or no) experience as a DM/GM/referee/judge and the "Running the World" chapter would provide you a solid education on how to approach a sandbox vs. the more modern storytelling structure of DMing. The provided game setting of the Realm of Arcem is outstanding. Kevin Crawford has provided not just an outline of the various nations and kingdoms of Arcem, but in depth information of each; he's done the worldbuilding for you. If running or playing demigods sounds intriguing I can't recommend this OSR based system enough. Well done Mr. Crawford!
