Dungeons & Dragons (D&D) is a tabletop role-playing game (TTRPG) that's been around since the 70s. At its core, it is a cooperative game where the goal is not to win or lose, but rather to tell a good story. With the Game Master serving as guide, narrator, and referee, players form a party of adventurers who embark on epic fantasy adventures. With the fate of the realm on the line, it all comes down to the party's choices – and the roll of the dice.
"From building confidence to processing trauma, tabletop role-playing games like Dungeons & Dragons are proving to be powerful tools for mental health. Science Quickly’s Rachel Feltman spoke to researchers and professional Dropout's dungeon master Brennan Lee Mulligan to explore how collaborative storytelling can help us thrive—and even be used as therapy." – Scientific American
Shows like Dimension 20 and Critical Role are frequently credited for bringing TTRPGs into the mainstream cultural conversation. What began as online shows on YouTube and Twitch evolved into animated TV series and live shows that have gone on to sell out venues like Madison Square Garden and the Hollywood Bowl.
