Join the Party is a narrative actual-play podcast built around serialized tabletop RPG campaigns, produced by the Multitude podcast collective. Episodes are recorded as in-character play sessions in which a regular cast — Julia, Eric, Amanda, and Brandon — narrates combat, dialogue, and worldbuilding decisions in real time, then periodically convenes in 'Afterparty' panel episodes to discuss what happened and why. The ongoing campaign uses Masks: A New Generation, a Powered by the Apocalypse superhero system, and follows teenage heroes Rowan, Connor, and Craft at a superhero high school in Lake Town City, confronting villains such as Fatberg, the Ooze, Obstructor Constructor, and demon-summoning rituals. Story episodes typically run 55 to 85 minutes and track serialized plot threads — villain reveals, character-power development like gravity manipulation and leadership moves, and consequences that carry across episodes, such as a school closure after a flood or a captured villain tied to a larger crime network. The Afterparty episodes function as behind-the-scenes discussion, with the cast reflecting on scene choices, character motivations, and how the game system shapes the story. The show occasionally pauses its main campaign for one-shot episodes with outside game designers, such as Fiona Shade's 'Democracy by Dice,' a community-organizing game built around a burnout mechanic. Listeners drawn to long-form collaborative fiction, superhero storytelling, and discussion of tabletop RPG mechanics make up the core audience, more than listeners seeking news, straight interviews, or short-form content. Production is dialogue-driven and largely unscripted, relying on cast improvisation and system mechanics rather than heavy narration. The show's history includes completed campaigns in other genres and systems (pirate, monster-of-the-week, high fantasy), indicating a pattern of rotating settings between long campaigns while keeping the same ensemble cast.
