Even if you’ve never played Dungeons & Dragons, you probably know someone who has: the game has had a profound influence on our culture, and 2014 marks the intriguing role-playing phenomenon’s 40th anniversary. Released decades before the Internet and social media, Dungeons & Dragons inspired one of the original nerd subcultures and is still revered by more than 30 million fans. Now, the authoritative history and magic of the game are revealed by an award-winning journalist and lifelong D&D player. In David Ewalt describes the development of Dungeons & Dragons from the game’s origins on the battlefields of ancient Europe through the hysteria that linked it to satanic rituals and teen suicides to its apotheosis as father of the modern video-game industry. As he chronicles the surprising history of the game’s origins (a history largely unknown even to hardcore players) and examines D&D’s lasting impact, Ewalt weaves laser-sharp subculture analysis with his own present-day gaming experiences, “writing about the world of fantasy role-playing junkies with intelligence, dexterity, and even wisdom” (Ken Jennings). An enticing blend of history, journalism, narrative, and memoir, sheds light on America’s most popular form of collaborative entertainment.
