A sold-out Madison Square Garden. Now MGM Grand Garden Arena. Somehow, a show where people sit around a table rolling dice and improvising fantasy stories has become arena-sized entertainment.
Tabletop chaos meets arena spectacle when Dimension 20 brings its signature blend of improv comedy and high fantasy to the Strip with Dimension 20 Live: Viva Más Vegas, a one-shot adventure designed specifically for the stage.
The beloved actual-play series, created by Game Master Brennan Lee Mulligan, has spent years building a devoted following on Dropout’s streaming platform. For the uninitiated, “actual-play” means exactly what it sounds like: Audiences watch players sit down and play Dungeons & Dragons in real time. Mulligan builds the world and voices supporting characters while core players each control a single character. Their decisions, combined with dice rolls, determine how the story unfolds. It’s improv comedy plus epic fantasy, and the magic comes from watching triumphs and disasters play out completely unscripted.
Mulligan’s reputation borders on legendary. His quick wit, encyclopedic imagination and willingness to push players into impossible situations help to create a show that consistently blends absurd humor with unexpectedly poignant storytelling.
The streaming show runs as an anthology series, with each season transporting viewers to entirely new worlds with fresh characters. Episodes clock in at two to three hours, packed with dense lore and house rules. Since launching in 2018 with Fantasy High, a coming-of-age story set at a high school for heroes, the show has explored candy kingdoms, haunted New York streets, sci-fi anarchies and Regency-era fae courts.
Dimension 20 has crossover appeal, too. Celebrity guests have popped into different seasons, including Critical Role’s Dungeon Master Matthew Mercer and RuPaul’s Drag Race stars Jujubee and Bob the Drag Queen.
For Dimension 20 Live, Mulligan will be joined by the show’s usual cast of characters: Lou Wilson, Ally Beardsley, Emily Axford, Zac Oyama, Siobhan Thompson and Brian Murphy. The chemistry among this core cast is a big reason Dimension 20 works. Over the years, they’ve guided fans through medieval intrigue, magical malls and sci-fi heists.
Dimension 20 Live is set as a one-shot, which means it’s a single, self-contained adventure. Who knows what lurks around the corner, be it the Rat King, a Celestial Paragon or maybe even the Faerie Mafia? The only certainty is uncertainty. In Dimension 20 Live, even the cast doesn’t know what’s coming next until the dice decide.
The leap from streaming to MGM Grand Garden Arena allows for immersive staging, elaborate visuals and full theatrical production. The players may still be huddled around a table rolling dice, but now thousands become part of an experience that is wholly unscripted and unpredictable. For fans, it’s a chance to experience the cast’s energy in person. For newcomers, it’s an entry point into what Mulligan calls “one of the most surprising, heartfelt and hilarious shows you’ve ever watched.”
Don’t know what you’re in for? That’s exactly the point.
