THE DUNGEONS & DRAGONS roleplaying game is about storytelling in worlds of swords and sorcery. It shares elements with childhood games of make-believe. Like those games, D&D is driven by imagination. It's about picturing the towering castle beneath the stormy night sky and imagining how a fantasy adventurer might react to the challenges that scene presents.
Unlike a game of make-believe, D&D gives structure to the stories, a way of determining the consequences of the adventurers' action. Players roll dice to resolve whether their attacks hit or miss or whether their adventurers can scale a cliff, roll away from the strike of a magical lightning bolt, or pull off some other dangerous task. Anything is possible, but the dice make some outcomes more probable than others.
In the Dungeons & Dragons game, each player creates an adventurer (also called a character) and teams up with other adventurers (played by friends). Working together, the group might explore a dark dungeon, a ruined city, a haunted castle. a lost temple deep in a jungle, or a lava-filled cavern beneath a mysterious mountain. The adventurers can solve puzzles, talk with other characters, battle fantastic monsters, and discover fabulous magic items and other treasure.
One player, however, takes on the role of the Dungeon Master (DM). the game's lead storyteller and referee. The DM creates adventures for the characters, who navigate its hazards and decide which paths to explore. The DM might describe the entrance to Castle Ravenloft, and the players decide what they want their adventurers to do. Will they walk across the dangerously weathered drawbridge? Tie themselves together with rope to minimize the chance that someone will fall if the drawbridge gives way? Or cast a spell to carry them over the chasm?
Then the DM determines the results of the adventurers' actions and narrates what they experience. Because the DM can improvise to react to anything the players attempt, D&D is infinitely flexible, and each adventure can be exciting and unexpected.
The game has no real end; when one story or quest wraps up, another one can begin, creating an ongoing story called a campaign. Many people who play the game keep their campaigns going for months or years, meeting with their friends every week or so to pick up the story where they left off. The adventurers grow in might as the campaign continues. Each monster defeated, each adventure completed, and each treasure recovered not only adds to the continuing story, but also earns the adventurers new capabilities. This increase in power is reflected by an adventurer's level.
There's no winning and losing in the Dungeons & Dragons game. At least, not the way those terms are usually understood. Together, the DM and the players create an exciting story of bold adventurers who confront deadly perils. Sometimes an adventurer might come to a grisly end, torn apart by ferocious monsters or done in by a nefarious villain. Even so, the other adventurers can search for powerful magic to revive their fallen comrade, or the player might choose to create a new character to carry on. The group might fail to complete an adventure successfully, but if everyone had a good time and created a memorable story, they all win.
