Editions of Dungeons & Dragons

Several different editions of the Dungeons & Dragons (D&D) fantasy role-playing game have been produced since 1974. The current publisher of D&D, Wizards of the Coast, produces new materials only for the most current edition of the game. However, many D&D fans continue to play older versions of the game and some third-party companies continue to publish materials compatible with these older editions.

After the original edition of D&D was introduced in 1974, the game was split into two branches in 1977: the rules-light system of Dungeons & Dragons and the more complex, rules-heavy system of Advanced Dungeons & Dragons (AD&D). The standard game was eventually expanded into a series of five box sets by the mid-1980s before being compiled and slightly revised in 1991 as the Dungeons & Dragons Rules Cyclopedia. Meanwhile, the 2nd edition of AD&D was published in 1989. In 2000 the two-branch split was ended when a new version was designated the 3rd edition, but dropped the "Advanced" prefix to be called simply Dungeons & Dragons. The 4th edition was published in 2008. The 5th edition was released in 2014.
