One of the First Dungeons and Dragons Developers Has Died

The original Dungeons & Dragons game came out in 1974, published by a company called Tactical Studies Rules, which later became known as TSR. TSR was started by Gary Gygax and created not only the first version of the game, but also Advanced Dungeons & Dragons. They oversaw the development of this popular tabletop roleplaying game until 1997, when Wizards of the Coast bought the company.
