GenJam: World-Building Edition is a hands-on, collaborative jam where creators use AI tools to design an original universe from the ground up—then bring it to life across multiple mediums.

​Teams will work together to define the core DNA of a world: its lore, geography, cultures, characters, aesthetics, and rules. Using cutting-edge AI image, video, and interactive tools, participants will rapidly prototype that world into cinematic teasers, short narrative videos, visual bibles, and—where time allows—playable or game-like experiences.

​TOOLS: We're using Wide Worlds, Rosebud, Plot Party, and Odyssey to build a world, vibe code a game in that world, and plot party to make a video of that world!

​This is not just about generating assets. It’s about thinking like world-builders: making creative decisions that stay consistent across story, visuals, and interaction. A city should feel the same in a trailer, a character reveal, or a game environment. AI becomes the accelerant, not the author.

​By the end of the jam, each team will present:

• ​A coherent fictional world (lore + visual identity)

• ​One or more short videos or trailers set in that world

• ​Optional extensions: game concepts, interactive scenes, or transmedia ideas

​GenJam World-Building Edition is ideal for filmmakers, game designers, writers, artists, and technologists who want to explore how AI enables rapid, collective universe-building—the kind used in modern franchises, games, and immersive storytelling.

​No prior world-building experience required. Curiosity, collaboration, and a willingness to experiment are the only prerequisites.
