Dungeons & Dragons is a fantasy role-playing game (RPG) originally designed by Gary Gygax and Dave Arneson, and first published in 1974 by Tactical Studies Rules, Inc. (TSR). The game is currently published by Wizards of the Coast, a subsidiary of Hasbro. It was derived from miniature wargames with a variation of the Chainmail game serving as the initial rule system. D&D's publication is widely regarded as the beginning of modern role-playing games and the role-playing game industry. D&D survives to this day and is enjoying new popularity largely because of an online version.
