Dungeons & Dragons 1974 - Japan Style Mug

Dungeons & Dragons (commonly abbreviated as D&D or DnD) is a fantasy tabletop role-playing game (RPG) originally designed by Gary Gygax and Dave Arneson. It was first published in 1974 by Tactical Studies Rules, Inc. (TSR). The game was derived from miniature wargames, with a variation of the 1971 game Chainmail serving as the initial rule system. D&D's publication is commonly recognized as the beginning of modern role-playing games and the role-playing game industry. D&D departs from traditional wargaming by allowing each player to create their own character to play instead of a military formation. These characters embark upon imaginary adventures within a fantasy setting. A Dungeon Master (DM) serves as the game's referee and storyteller.
