Dungeons & Dragons (D&D) is a fantasy tabletop role-playing game created by Gary Gygax and Dave Arneson and first published in the United States by Tactical Studies Rules (TSR) in 1974. It is widely regarded as the first commercially successful modern tabletop role-playing game and played a major role in establishing role-playing games as a distinct form of entertainment.
D&D developed partly from miniature wargaming, particularly Gygax and Jeff Perren's Chainmail, but replaced the control of armies with individual fictional characters. It also drew on fantasy, mythology and adventure literature, including works associated with J. R. R. Tolkien and The Lord of the Rings, alongside many other literary and historical influences.
In a typical game, each player controls a character with abilities, equipment and a character class, while another participant serves as the Dungeon Master (DM). The Dungeon Master describes the fictional world, controls its inhabitants and challenges, and interprets the rules. Players explore locations, interact with non-player characters, solve problems and engage in combat, usually using polyhedral dice to determine uncertain outcomes. Characters commonly gain experience and become more powerful over the course of a campaign.
The game expanded rapidly during the late 1970s and 1980s and was published in numerous editions and variations. TSR was acquired by Wizards of the Coast in 1997, which itself became part of Hasbro in 1999. D&D has since developed into a large multimedia franchise encompassing novels, campaign settings, board games, computer games, films and other licensed works.
Influence
Dungeons & Dragons had a major influence on fantasy gaming and popular culture. Many concepts that became standard features of later role-playing games, including character classes, experience points, levels, hit points, parties of adventurers and numerical character attributes, were popularised through D&D. The game also encouraged a form of collaborative storytelling in which players could create persistent characters and fictional worlds rather than follow a predetermined sequence of events.
Its influence was particularly important in the development of role-playing video games. Early programmers attempted to reproduce the experience of tabletop D&D on university and personal computers, converting dice rolls, character statistics and dungeon exploration into software systems. Early computer role-playing games were followed by major series such as Ultima, Wizardry and later Baldur's Gate, while concepts derived from tabletop role-playing spread throughout the wider video game industry. Systems involving experience points, character levels, classes, equipment and numerical attributes are now found in genres far beyond traditional computer RPGs.
D&D also became an important influence on later tabletop games, fantasy fiction and other forms of interactive entertainment. Its success helped turn role-playing from a small wargaming hobby into an international form of gaming and contributed to the development of both tabletop and digital role-playing culture.
