A thorough and interesting look at the business side of the gaming business. The book assumes some knowledge about the history of D&D as a game on the part of the reader - if you don't have a basic familiarity with, say, Blackmoor, you're not going to learn it here. But things like that have already been written about extensively elsewhere, and this book breaks new ground by documenting the game's evolution as a business up to the ouster of Gary Gygax in the mid-1980s, and does so in a lively way in spite of the book's focus on corporate minutia.
