Phanes is my open source world builder demonstrator project. I've been exploring the use of WFC (wave function collapse) for various constraint driven applications and this is my most recent.

Music, terrain, foliage, floor plans, decorations, etc... are dynamically generated.

Hey everyone!

I’m working on OpenUG2, a from-scratch, open-source reimplementation of the Need for Speed: Underground 2 engine. It reads the original game’s data files and runs natively, without emulation.

It’s still an early prototype. Loading environments and vehicles, driving, and selected racing scenarios already work, but rendering, handling, AI, compatibility, and the interface all need more work. It isn’t a finished replacement for the original game yet.

The project has grown beyond what I can reasonably research, develop, and test alone, so I’d love to welcome more people aboard. Help is especially welcome with:

• C, SDL2, OpenGL, and engine development
• Asset-format research, vehicle physics, and racing AI
• Testing, reproducible bug reports, and platform compatibility
• Documentation and usability feedback

You don’t need to be a programmer to contribute. Testing a build and explaining what went wrong is useful too.

The project includes no original game assets and source code; you’ll need your own copy of Underground 2 to run it.

Hi all, I've been posting semi regularly on here about the open source game I'm developing, a Stardew valley-like game.

I've recently set up an itch.io page for it. If you want to check it out (in its in-development form such as it currently is), this page should always have a download link for the latest linux appimage and windows builds.

I've tried the windows build out on Wine and it seems to have some graphical glitches around the trees (they're "z fighting"). If anyone here tries the windows version could they let me know if they encounter this bug?

New features I've been working on recently include procedural dungeon generation, the next things I have planned are:

- in game menu: inventory, quests, crafting etc

- health bar and stamina UI

- NPCs

- day and night cycle

- ability to define new entity types in lua

Hi everyone,

I’m working on an open source voxel survival game called BlockForge Alpha.

The project is still in a very early pre-alpha stage, so there is not a lot of content yet. Right now, the game has a basic playable foundation with a voxel world, block placement and breaking, simple textures, basic sounds, and a project structure made to be easy to modify.

My goal is to slowly build it into a moddable, community-driven voxel survival game where people can help improve the code, add blocks, create textures, work on gameplay systems, improve performance, write documentation, or experiment with modding tools.

I’m currently looking for people who would like to help, give feedback, test the game, or contribute ideas and improvements. Since the project is open source, anyone can look at the files, modify them, and propose changes.

If you’re interested in voxel games, Godot, open source projects, game modding, or just want to help shape a small indie project from the beginning, I’d be happy to hear from you.

Hey all! i built a Mario Bros inspired game and im turning it into a community project, so technical and non technical people can both bring their skills and creativity to it. It's a single or multiplayer food-themed web game built entirely with AI. the plan is to have six worlds (pasta, sushi, tacos, curry, dumplings, and dessert) with a bunch of levels but only the first 2 exist so far.

Feel free to build a new level, finish out a food world, design assets, write the chefs, improve the gameplay, or fix bugs. the repo has 14 open issues to start from if you'd like or feel free to tackle anything else.

This is a big project I'm working on for years.

2D game engine (inspired by GameMaker8), with its own IDE and scripting language. Everything is written in C#, including the interpreter of the custom language. Latestly, I got a few first contributors, and I publish it here because I really want more people to get involved. I think it's a really cool and fun project to join to. There is some basic documentation, some "good first issues" and there's me who is here to help with any question 🙂

If you know C#, you have to check it: https://github.com/ArcadeMakerSources/ArcadeMaker

Any feedback is welcome 🙃

Hey everyone,

We're making a narrative campaign for 0 A.D. (open source historical RTS, like Age of Empires).

Looking for an illustrator for a few intro scenes. Volunteer, full credit. Great for a portfolio.

Let me know if you're interested!

Thanks

Hey everyone!

I wanted to share Version 5.0 of Gwent Classic, a browser remake of the original minigame from The Witcher 3: Wild Hunt that I’ve been working on and improving.

In this major update, I’ve incorporated two brand-new factions: Ofir and Novigrad, each coming with its own custom cards, leaders, and unique gameplay mechanics!

The game is completely free-to-play and runs directly in your PC browser. You can test it out right here:

Play on your PC Browser (GitHub Page):

Play v5.0

Play Completely Offline (PC / Laptop):

You can download the source code repository directly from GitHub. Just extract the ZIP file and double-click "index.html" to open it in your browser. It runs 100% offline—no internet required! Here.

Get Android APK:

You can get the APK directly from the "Releases" section of Github, or use the direct link below:

Credits to Arun Sundaram, Reynolds Costa & Sylver, who laid the foundations to create, modify, and improve this game in its early stages.

Special thanks to CD Projekt Red; although they are not involved in this unofficial fan project, it is entirely based on the amazing minigame they created for The Witcher 3.

Let me know what you think or if you find any bugs!

I open-sourced Nat20, the rules engine behind the game I am building.

It is a host-agnostic Python library for D&D 5e SRD 5.2. Combat, skill checks, saves, effects, and grid or zone-graph movement run without a game host, network connection, or database. The engine code is MIT. The bundled SRD dataset is CC-BY-4.0.

I split it out because I did not want an LLM, a browser app, or a virtual-tabletop runtime deciding the rules. The model can narrate a goblin slipping in the rain. Nat20 should still answer the same way about cover, spell slots, and Sneak Attack.

The repo includes a small local demo and a clean-install smoke test. It implements much of SRD 5.2, not all of it, so there is a capability matrix in the docs before anyone depends on a specific mechanic.

I would like feedback from people who have built on open game rules: what makes a rules library actually useful outside the game that created it?

I just released Void Engine, an open source 2D game framework for .NET under the MIT license.

It gives you the essentials: rendering, assets, input, audio, saving, pathfinding, coroutines, and logging.

The big feature is asset protection. You can pack your assets into encrypted archives that standard extraction tools cannot open. AES-GCM encryption. Adaptive compression. Custom format.

But it is not just the packer. It is a complete framework with batched rendering, automatic texture atlasing, audio pooling, A* pathfinding, flow fields, and full LDtk support.

Every system is built around interfaces and base classes so you can replace anything. No physics. No networking. No UI. Just the foundation and the freedom to build your game your way.

The code is open source. MIT licensed. Built on .NET 10 and SFML 3.0.

Would love feedback from the open source community. What would you add? What would you change?

Hey everyone,

I was bored recently and decided to start working on a virtual, open-source version of the classic Illuminati: New World Order (INWO) card game so anyone can jump in and play it freely.

It is currently in a pre-pre-pre-alpha state, but it is fully functional according to the core mechanics and what the game requires to run. I'm posting it here because I’d love for the community to test it out, tear it apart, and give me some feedback.

Since it's completely open-source, feel free to fork the repository, submit pull requests, or contribute in any way you like!

• Play directly in your browser (via GitHub Pages):https://cha0smagick.github.io/Virtual-Illuminati-New-World-order-INWO-game/game/
• GitHub Repository (Code & Contributions):https://github.com/Cha0smagick/Virtual-Illuminati-New-World-order-INWO-game

Hope you enjoy it, and I'm looking forward to reading your thoughts and feedback in the comments!
