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 - A list of different open-source video games and commercial video games open-source remakes.

Space Station 14. Outrageously fun, deep, rewarding, hilarious, insane game. I can't recommend it highly enough. The learning curve for basic controls can be a lot, but it's so worth it.

The third link has it, but not the first.

Here's my Mastodon thread on one of my favorite SS14 rounds, which I got quite a few videos of: https://packmates.org/@noxypaws/115755081201489367

Another RTS suggestion, OpenRA: https://www.openra.net/

CC non-commercial is not a free license. FSF lists it under documentation licenses because it doesn't recommend any CC license for software but the concerns are still valid.

Note that selling copies of free software is explicitly encouraged; free refers to freedom (specifically the "four freedoms") and not to price.

RTS: 0.A.D.

FPS: D-Day:Normandy

Hypnagonia. A FOSS Slay The Spire-like game. I made this one ^_^

[–] bruce965@lemmy.ml 3 points 18 hours ago (1 children)

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.

[–] db0@lemmy.dbzer0.com 4 points 17 hours ago* (last edited 17 hours ago) (2 children)

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.

[–] Carrot@lemmy.today 1 points 4 hours ago

While I understand where you're coming from, I think this list exists for a different purpose than to find you collaborators. While I didn't make the list, I do like having a list of competed FOSS games somewhere, as I think it fills a gap in FOSS game reporting. I think there should be (and know there are) other lists specifically for FOSS games looking for collaborators.

[–] bruce965@lemmy.ml 5 points 16 hours ago

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.

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.

[–] morto@piefed.social 5 points 23 hours ago (1 children)

I have this other bookmarked link that may be helpful:

[–] bruce965@lemmy.ml 1 points 9 hours ago

Thanks a lot. This seems to be a very complete list, I will have a look and see which ones match my criteria. If you have any one you like in particular, feel free to share.

Thank you for this recommendation, but although the code is GPL-2.0, some of the assets for BAR are proprietary.

[–] eleijeep@piefed.social 2 points 9 hours ago

I didn't know that, but I also noticed after posting that on the download page they describe it as "alpha+" so that would also disqualify it from your list.

[–] Techlos@lemmy.dbzer0.com 9 points 1 day ago (2 children)

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

[–] bruce965@lemmy.ml 1 points 9 hours ago

Hi! Although the engine is free, the game assets seem to be proprietary. Still thanks for sharing the suggestion.

[–] Chulk@lemmy.ml 6 points 1 day ago (1 children)

Holy shit. I played the shit out of this game when I was a kid. I had no idea someone ported it like this.

[–] Techlos@lemmy.dbzer0.com 2 points 1 day ago

There's even an android port, although it's pretty hard to do the ship twiddles on touchscreen lol

[–] yakko@feddit.uk 5 points 1 day ago (1 children)

I'm so glad to hear someone liked Strife enough to do a port of it. I did not do well trying to play that thing as a dumb kid, but I was entranced by the tone and scope of it. Probably had something to do with my ttrpg writing habits.

[–] InFerNo@lemmy.ml 2 points 6 hours ago

Strife was great. Soft locking your game because you made the wrong choice or attacked the wrong guy was really special to me. Good memories.

[–] morto@piefed.social 4 points 1 day ago (1 children)
[–] bruce965@lemmy.ml 1 points 9 hours ago (1 children)

Thank you a lot, this also seems to be a great list. And it comes with list of lists as well! I will have a deep look and see which games match my criteria.
