As the men and women who played Dungeons & Dragons during the games heyday have entered middle age, there’s been a growing number of them who have chosen to write about the game. Some, like Ethan Gilsdorf’, author of the highly-recommended Fantasy Freaks and Gaming Geeks, focus on the game’s role in their own lives and that of other enthusiasts. Others, like Mark Chadbourne, author of The Elfish Gene, revisit their years with Dungeons & Dragons in the form of cringe-worthy bildungsromans. Until now, there hasn’t been a serious exploration of the business side of the game, from its birth on a Wisconsin card table to its eventual transformation into a cultural phenomenon. Forbes writer David M. Ewalt (a gamer himself) has taken up this challenge in his book Of Dice and Men: The Story of Dungeons & Dragons and the People Who Play it.
