What is the source of this emotion? It is the recognition of sincerity behind the silliness. The players are not mocking the genre; they are elevating it. When a goblin cleric sacrifices her last spell slot to save a dying friend, the audience feels it because the players feel it.
But Mulligan defies the “tyrant GM” trope. His style is a high-wire act of radical acceptance. When a player rolls a natural 1 (a critical failure), he doesn’t punish them. He celebrates them. “Failure is the spice of life,” Mulligan says between seasons. “If you only roll 20s, you aren’t playing a game. You’re reading a brochure.”
His genius lies in tone calibration. One moment, he is voicing a lecherous, gum-chewing candy wizard in The Unsleeping City ; the next, he is delivering a devastating soliloquy about mortality and class warfare in A Crown of Candy (a season famously pitched as “ Game of Thrones meets Candyland ”). The rotating cast—known as the “Intrepid Heroes” when the main ensemble plays—is a murderer’s row of improvisational talent. Ally Beardsley (known for chaos agent gameplay) once derailed an entire final boss fight by casting a spell to turn the villain into a cockroach. Emily Axford (a tactical genius disguised as a goblin) regularly solves puzzles in ways that make Mulligan visibly sweat. Brian Murphy, Siobhan Thompson, Zac Oyama, and Lou Wilson round out a group whose chemistry is so refined that they can communicate entire character arcs through a single shared glance.
But the legacy is already written. Dimension 20 proved that actual play doesn’t have to be a podcast you fall asleep to. It can be a vibrant, cinematic, hilarious, and heartbreaking art form. It proved that a bunch of improv nerds around a plastic table can build a cathedral.
