Polarisation. Cost of living. Inequality. Climate change. Technocrats. Do you believe our current systems of democracy are up to the task of fixing these insanely huge issues?
No? Then it’s time to assemble.
Citizens’ assemblies give ordinary people the structure and power to come together and actually resolve the issues we're all facing. Like jury service on steroids, they bring people together from all walks of life to learn, debate and find solutions.
The good news? They’re proven and already making a difference around the world. The bad news? No one knows about them.
That’s where video games come in.

Assemblies are gatherings of regular people (usually 100-150), brought together to discuss thorny issues - everything from regenerating a town square to the global climate crisis - and find solutions to them. People are selected to be a true snapshot of a place based on demographic criteria such as gender, age, income and education level. Through carefully crafted structures, they deliberate together on the key problems, causes and solutions. The outcome? A series of nuanced, realistic recommendations that most often go farther than politicians do - and that truly represent the voice of the population. |
One World or None (OWON) exists to help radically improve political decision-making on critical global challenges by amplifying the agency of ordinary people. It is a cultural campaign to create mass awareness of and advocacy for citizens’ assemblies globally and to inspire a movement for this new democracy of citizen participation.
Global Game Jam (GGJ) is a 501(c)(3) nonprofit whose mission is to empower all individuals worldwide to learn, experiment, and create together through the medium of games in a safe and welcoming environment. By holding the world's largest game creation event and directly serving 40,000 game creators every year in 100+ countries, GGJ works to support their jammers through community engagement, partner jams and more.

This jam is for 18+
• Submissions will be handled via the event page on itch.io. Teams must also submit a brief application and 1-3 page high level Game Design Document (GDD) to accompany their submission. This will include full team information and any relevant links to previous work.
• Games should be web-playable with a design for mobile in consideration - not exclusive to any operating system (can be ios, android, etc.)
• Only one team member needs to upload the game, but be sure to credit all other contributors as game authors. On your game's itch.io page, go to Edit → More → Admins and follow the instructions to add them.
• You can update and improve your submission as many times as you like before the deadline. The final version submitted before the cutoff will be considered for judging.
• Do not update your game during the public voting phase. Any changes to your game build, re-uploads, or deletions during this period may result in disqualification.
• Submitted games must use English as the default language.
• There are no restrictions on the development platform or game engine used. However, you must provide a build that runs on either Windows or Mac as part of your submission.
• Games created within other games (such as Super Mario Maker, Dreams, Roblox, etc.) will not be accepted.
• Participants must own the rights to all software and assets used in their submission, or use properly licensed open-source resources.
• All copyrights for submitted games remain with the creators. However, by participating in the event, you agree to allow One World or None to showcase your submission on their websites and at related offline events.
• If your game includes any "AI-generated assets", you must clearly state this in your game description, including which parts of the game were created using AI technology. Failure to disclose the use of AI assets may result in disqualification.
• Please note: No legal protection or support will be provided in the event of copyright disputes arising from AI-generated content.

The goal is to bring assemblies to the world's attention - to achieve mass awareness and approval from millions of people.
The game jam - alongside a lot of other initiatives in film, TV and more - is just the first step of this.
Our hope and intent is to help take one game from prototype to full release, with a view to getting it downloaded far and wide around the world.
This will depend on a number of factors, so it's hard to make solid plans until after the jam. Stay tuned.
