Libre games thread

Apparently this used to cost back in the day but since then the devs made it and the 70ish asset packs free (excluding a couple because the original artists were stingy). As far as game maker engines goes it's complete shit but stumbling across this when I was small had a massive hand in forming my appreciation for game development. As well there used to be a bit of a community surrounding this engine with some popular mods including the Black Ice multiplayer mod (might have botched the name).

For a kid's first encounter with proper game dev this engine is actually pretty sick.

Oh and as well there's M.U.G.E.N
If you like fighting games or like any character from anything ever I'm sure you can find some enjoyment in M.U.G.E.N. Even gamblers love it because of Salty Bet

Btw, awesome thread, OP. I only clicked on to see what it was but this is actually a super cool list to have so sorry if these don't count and I messed it up

MUGEN as a fighting engine might be free but the moment you added all those copyrighted characters it's copyright infringement, trademark infringement or both.

Doom is great but I think this is the only aspect it cannot fulfil:

The freedom to redistribute copies so you can help others.

The game is still copyrighted and sold (on Steam or other stores) so you cannot really redistribute copies like that or else it's considered as piracy (although I don't care that much if someone got the Iwads online).

For those interested, there's a fork called Freedoom which replaces all the games assets (everything that's not the code itself, which is already under GPL) with new ones that are libre.

I'm currently doing Phase 2, it really feels a bit like a bootleg "Doom at home" but the engine itself is strong enough to make it feel good.

Pretty much every game I came here to talk about has already been mentioned. There's quite a few pretty good FOSS games around that you can play nowadays. DOOM itself is almost fully libre now, but you can use the FreeDoom assets (and play their own original campaigns, which are pretty good!) to run pretty much any community created map pack or mods, on one of the many freely available sourceports.

Then, there are several other games that aren't necessarily just a reimplementation of a beloved classic. Luanti started out as "Minecraft at home" but it's quite a bit more now, even though most played games in that engine are still Minecraft-likes. I recommend trying out Asuna on their content page, it's a nice base for modding. I don't think I need to explain OpenTTD, the classic transport management game. Battle For Wesnoth is a very nice fantasy wargame, with RPG elements and story campaigns. BAR is probably my favorite modern RTS game of all, just an incredibly good time. And, lastly I have to mention MegaMek - the free implementation of Battletech Classic rules, that I've been playing A LOT lately.

I think Cube 2 Sauerbraten and Warsaw are both Open Source? I need to verify.

Is there a site referencing every games that are FOSS?

I'm pretty sure that they are, and on this vein, I forgot to mention Xonotic! Great arena shooter, super fast and something in between Quake and Unreal Tournament. Which are both also, effectively free nowadays, with OpenArena, QuakeWorld and OldUnreal...
