From Wired:

Gary Gygax, one of the co-creators of the Dungeons & Dragons role-playing game, died Tuesday morning at his home in Lake Geneva, Wisconsin, according to Stephen Chenault, CEO of Troll Lord Games. Gygax designed the original D&D game with Dave Arneson in 1974, and went on to create the Dangerous Journeys and Lejendary Adventure RPGs, as well as a number of board games.

Gygax’s legacy is that he helped to create much of what we now call gaming – be it with dice, on a computer, or on a console. His game was played by pretty much everyone my age (well, the males, anyway). He certainly won’t be forgotten.
