Dungeons & Dragons is a structured, yet fundamentally
open-ended role-playing game. It is normally played indoors with the
participants seated around a tabletop. Typically, one player takes on the
role of Dungeon Master (DM) while the others each control a
single character, representing an individual in a fictional setting. When
working together as a group, the player characters (PCs) are
often described as a "party" of adventurers, with each member often having
their own area of specialty which contributes to the success of the whole.
During the course of play, each player directs the actions of their
character and their interactions with other characters in the game. This
activity is performed through the verbal impersonation of the characters
by the players, while employing a variety of social and other useful
cognitive skills, such as logic, basic mathematics and imagination. A game
often continues over a series of meetings to complete a single adventure,
and longer into a series of related gaming adventures, called a
"campaign".
