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.
Hypnagonia. A FOSS Slay The Spire-like game. I made this one _
Hi! So nice to see you here!
I hope you don’t mind, I would prefer to only keep finished games on this list. There already are lots of awesome curated lists which include pre-release FOSS games.
Is any FOSS game really every “finished”?
In any case, Hypnagonia is “finished” in the sense that you can play a run end-to-end. It just could use more content, but being excluded for such lists doesn’t help find collaborators.
Fair enough, in that case let’s add it. But if you don’t mind me sharing my opinion: you say everywhere that it’s a pre-release software, and the 0.x.x version supports this hypothesis. If you think it’s ready to be considered a completed project (but not necessarily also finished) you might want to be more explicit about it.
A suggestion - open Tyrian
https://github.com/opentyrian/opentyrian
One of the greatest shmups ever, the creator open sourced it a while ago. Still weirdly addictive too, only DOS era game I still play regularly
Holy shit. I played the shit out of this game when I was a kid. I had no idea someone ported it like this.
There’s even an android port, although it’s pretty hard to do the ship twiddles on touchscreen lol
Hi! Although the engine is free, the game assets seem to be proprietary. Still thanks for sharing the suggestion.
RTS: 0.A.D.
FPS: D-Day:Normandy
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.
Thank you very much, I will have a thorough browse and filter the games that match my requisites. If you have any one you like in particular, feel free to share.
Maybe it is better to avoid duplication of effort and contribute to OSGL.
You just need to add a “mature” tag to it and a option to filter by it. contributing to it is easy as far as i can tell.
They seem to be a bit more lenient than me. Their list also includes games which depend on non-free assets, as long as the source code is free. Still, I will add this list to the list of lists in the post. Thanks!
A FOSS lemmings clone.
Added, thanks for the suggestion! They tricked me with the 0.x.x version identifier, but it seems to be a mature/completed project.
Another RTS suggestion, OpenRA: https://www.openra.net/
Hi! Although OpenRA’s source code is free, it depends on proprietary assets, so unfortunately it doesn’t qualify for this list. Still, thanks for the suggestion, CnC and RA were both amazing games!
I checked the website and you’re right, the game engine is free but the mods require files from the original games.
