Dungeons and Dragons is the most popular tabletop role-playing game of all time. The game is played with about 6 players. One person takes the role of storyteller, AKA the Dungeon Master, and narrates the story in a medieval fantasy world filled with magic, monsters, romance, intrigue, and adventure. The rest of the players take on the roles of individual fictional characters and explore that world, often becoming heroes in the story. The story is like a completely interactive "choose your own adventure" book. Different shaped dice are used to determine the outcome of attempted actions.
Scheduling games of D&D is a little more complicated than just showing up for a game. There are three different ways people assemble to play D&D.
We have the "open to all" meetups that are on the first Saturday of the month in Manhattan and the third Sunday of the month in Brooklyn.
We have the RPGA Organized Play meetups which are every Tuesday night.
We have "Campaign Gaming" where DMs run longer adventures that span several weeks.
