The Rise of the Dungeon Master Reviewed in the National Post
From the review:
D&D engages players unlike any other game, allowing for the creation of infinite characters and worlds. It’s that level of engagement that grew the company to a $16 million a year business in under a decade. And that first generation of fans had the same instincts as Gygax, to improve and expand the game. As the book shows, D&D rules were easily adaptable to computers, which led to the development of the first rogue-like dungeon crawler computer games, then more advanced games like Ultima, and finally the massive multi-player online games of today. Those computer games and dozens of imitators, and perhaps even the whole gaming industry, owe their existence to D&D.
