Dungeons and Dragons

Dungeons & Dragons  (  D&D )  is a  fantasy ,  role-playing game  (RPG) originally designed by  Gary Gygax  and  Dave Arneson, and first published in 1974. The game has been published by  Wizards of the Coast  since 1997. 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 departs from traditional wargaming and assigns each player a specific character to play instead of a military formation. These characters embark upon imaginary adventures within a fantasy setting. A Dungeon Master serves as the game's referee and storyteller, while also maintaining the setting in which the adventures occur and playing the role of the inhabitants. The characters form a party that interacts with the setting's inhabitants (and each other). Together they solve dilemmas, engage in battles and gather treasure and knowledge. In the process the characters earn experience points to become increasingly powerful over a series of sessions.
