Before you apply

Gotta read the fine print...

AT Jam Dole provides $750 USD per team member for a focused, two-week game development cycle on a specific prototype leveraging AT Protocol technologies. It is temporary prototype funding, not employment or a guaranteed ongoing income.

Selected teams commit to making a complete, playable game and sharing progress during the cycle. Final builds will be featured on the atmosphere.games catalogue and shared as part of a playable showcase at Playtopia Festival as part of their completion.

To complete a cycle, the game must be playable from start to finish, have functional controls and clear goals, and be published publicly with enough information for people to understand and play it. After a successful submission, each funded team member must submit an invoice to The Playtopia Foundation NPC. Selected projects will have part of their game pitch shared publicly.

Funding is forfeited if a submission is materially incomplete, substantially altered from the approved prototype without agreement, plagiarized in whole or part, made with unauthorized or illegal content, or submitted late without an exemption.

All intellectual property, game rights, and related materials remain the property of the respective creators. AT Jam Dole nor any of its partners claim any ownership of your work. You are free to license, distribute, and exploit your creations at your liberty.

Games on AT Protocol

What is AT Protocol?

AT Protcol (aka atproto) is an open web technology that allows users to control where their online content is stored, validate their identity across multiple apps, and utilize the various data they create across different experiences. It is the underlying technology behind Bluesky, and a growing number of games, sites, and more which we call the Atmosphere.

Why does it matter?

The large tech companies that control a majority of online data are increasingly holding it hostage to prevent users from leaving their platforms, isolating what services can leverage it, and enforcing their own opaque moderation controls that prevent a truly competitive online ecosystem.

Open web technologies like AT Protcol shake that up by returning control to the user, allowing them to switch providers without losing content or followers, and improves the online ecosystem by allowing developers to fairly leverage data that would otherwise be locked behind monopolistic tech platforms.

Okay, but... games?

ATmosphere Games is a showcase platform for the many games currently leveraging AT Protcol in some way. Some games use the technology to let players log-in with their existing Bluesky accounts, while others go further and create persistent stat, inventory, or character records that stay in the player's universally recognized account.

One of the most exciting features of games on AT Protocol is their capacity for new sorts of interoperability. Where one game may provide a user with an item they can keep, another game might choose to recognize it within its own context. Developers can choose to leverage the technology in ways that make their games more connected.

Interesting... give me a literal example?

Titles like 2048.social and Throng pull from the player's Bluesky follower list to render friendly faces as part of the experience. Meanwhile, Spaceships and Race The Sky hold high scores your friends can compete against.

Many players have visited rpg.actor and produced a 2D sprite avatar for themselves. When they use their Atmosphere Account to login to various games like Clun's Cannon or Chaos Soccer, those games load the player's sprite and use it as their in-game character. Both of these games provide players with special equipment (like these Clown Shoes or Soccer Ball) which offer the player benefits within the other game.

There are a wide range of potentials for how games can utilize AT Protocol, and we are only starting to figure out all that can be done.

Can my AT Protocol game still sell on Steam?

Yes! Your game's use of AT Protocol is entirely based on its web access, and can exist as a standalone title or sold on any storefront.

What engines support AT Protocol?

Any game engine that can interface with the web or make XRPC calls can utilize the technology. There are already community-built plugins available for Godot and RPG Maker, with some for Unity and Unreal expected to release soon.

You can follow along and contribute at the AT Games Workgroup.
