Dungeons & Dragons (D&D) is a tabletop role-playing game (TTRPG) created by Gary Gygax and Dave Arneson and published by Wizards of the Coast. This dynamic game encourages players to explore fantastic settings, flex their creative muscles, and foster connections with others, regardless of whether they are sitting across a table or across the globe. In this volume of The Psychgeist of Pop Culture, we explore psychological concepts relating to the lore, gameplay, and culture of Dungeons & Dragons, with a focus on understanding and showcasing why it is the most influential TTRPG of our time.
