Build a Better World TTRPG jam banner

“We live in capitalism,” said Le Guin, “Its power seems inescapable. So did the divine right of kings.” It’s up to us, as games makers, to help people envision alternatives to how we live now, how we can build a better world.

TTRPGs are a fantastic way to build community and bring solace in harrowing times. Many of us, all over the world, are going through difficult and anxious days. With the community at The Lost Bay server we’ve decided to host this jam as a space for the indie TTRPG scene to come together and imagine a better future.

The jam lasts until summer solstice on June 21st 2025. During the jam you’re invited to craft TTRPG material: a game, an adventure, a setting, a player handout, something, anything!

The jam is open to any system and any kind of game, as long as you follow the rules and guidelines below. You can write about goblin revolutions, post-apocalyptic house-builders, space fantasy maintainers of intergalactic love streams or anything else you can imagine.

If you’re looking for friends and collaborators, folks to share your visions of a new brighter world and RPG project, jump on The Lost Bay server. During the jam various public events will be held, such as online/IRL workshops, game sessions. Subscribe to The Dispatch newsletter to get news about the jam.

SRDs

System Reference Documents AKA cool games you can hack

  • https://tunnelgoons.com/srd Tunnel Goons is a simple table-top role-playing game. It's a light weight 2d6 system that can be applied to many different genres and settings.
  • https://fari-rpgs.itch.io/breathless-srd The Breathless SRD is a creation toolkit that helps you design a game where every mechanic ever-increasingly rises the tension until the characters are forced to suffer dangerous consequences.
  • PUSH SRD https://capacle.itch.io/push A story-driven, stat-free system for games that want lots of action without a lot of number crunching. Built on an easy to grasp push-your-luck mechanism.
  • CHARGE SRD https://fari-rpgs.itch.io/charge-srd What if Forged in The Dark was super lightweight? You’d get something that looks like this. Players can explore and challenge an existing world, instead of building one around themselves.
  • Second Guess SRD https://gamenomicon.itch.io/second-guess-system-srd If you have 1d20, 1d6, and want to write a profoundly weird one-page solo game, the Second Guess system was written for you.
  • Caltrop Core https://titanomachyrpg.itch.io/caltropcore When you need bare-bones elegance, it doesn’t get more condensed than “roll 1d4 to determine degrees of success and failure.”
  • A more complex version of Caltrop Core: https://titanomachyrpg.itch.io/ccex
  • PASSKEY SRD https://penflower-ink.itch.io/passkey-srd This system allows players to choose between spending points and testing their luck to achieve varying degrees of success. Great for strictly narrative games. (Known for Stravagante!)
