I decided to write down a list of complete (no alpha/beta), playable (no proprietary dependencies), FOSS videogames.
I added all the games I could find online + all of the games that came to my memory.
Feel free to have a look to see if there’s something you didn’t know. And please suggest anything I missed, but please do not suggest pre-release or unfinished games.
Thank you!
EDIT: thank you very much everyone for the comments and for sharing additional awesome lists of FOSS material. Hopefully one day I will have the time to sift through all these games and pick all the non-pre-release ones which don’t have any proprietary dependencies.
In the meantime, here’s a copy of the links:
- LibreGameWiki - A wiki of free games and related topics started by Han Dao.
- Open Source Game Clones - Open-source or source-available remakes of great old games in one place.
- Open source games (bobeff) - A list of different open-source video games and commercial video games open-source remakes.
- Open Source Games (trillarion) - A list of open source games, game frameworks and game creation tools.



Hi, thanks for the suggestions. Unfortunately 0 A.D. is still in beta, so it wouldn’t qualify for this list yet. It’s definitely popular enough to deserve to be in the honorable mentions though, so I will add it.
As for D-Day:Normandy I assume you mean this? I can’t seem to find a license (nor source code actually, but maybe there is no source code as all scripts might have been written manually). I could add it if it’s actually FOSS, but I’d need help about the license and where to find sources.
In your link, the source is in the src folder
The license is GPLv2. I believe the file is called GNU.TXT in the repository, at least that’s what I have in mine https://github.com/InFerYes/dday
Additionally there’s LICENSE.TXT with some information by Id Software, who open sourced the engine on which this game is based.
My repository’s code is what runs on the active servers. Powabanga’s has installers for the clients.
