D&D

n. (Trademark) popular fantasy role-playing game

Dungeons & Dragons (abbreviated as D&D or DnD) is a tabletop fantasy role-playing game (RPG) originally designed by E. Gary Gygax and Dave Arneson, and first published in 1974 by the Gygax-owned company Tactical Studies Rules, Inc. (TSR). The game is currently published by Wizards of the Coast, a division 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, by extension, the entire role-playing game industry.
