Great suggestions in this discussion! Rather than adding my favourites, I will add some resources that list more games.
Libregamewiki: it is really comprehensive (sometimes too much, including even not-so-good-games). They care about licencing and is is very easy to browse, top-notch for me.
Open source games: a more relaxed repository, with lots of material.
bobeff open source list: this is curated, which means that there are not so many games but each and every one is stable, good, maintained.
Arcane Cache: a fantastic blog with reviews of libre games — or more precisely, underground games, there is a lot of discussion on how gamedevving philosophy too. The reviews are always in-depth and allow you to experience the games on another level, and each game is a small jewel in its category. Strongly recommended!
Some of the most polished open source games are: 0 A. D., Xonotic, Beyond All Reason, Battle for Wesnoth, Mindustry, Minetest, Thrive. These are all great games open source or not. I'm sure I'm missing a few, but these stand out to me for their completeness and polish.
I wasn't expecting to find a new "polished" open source game I've never heard of from this thread, but somehow I've never heard of Thrive before. It's even got a steam release!
Battle for Wesnoth is the one that comes to mind first. Turn based strategy game.
Dungeon Crawl Stone Soup classical roguelike, as in actually like Rogue/nethack. Can be played with ASCII or graphical tiles, and you can play in a browser window with scoreboards and a spectator mode.
I suspect I didn't explain myself well.
If I remember correctly, you can enter and exit the campaign, and doing so saves the game. There is also a single autosave, which you can't manually select and is there for better or worse.
So in practice, one mistake or ruthless surprise can turn into a lot of wasted time. For the sake of my alopecia, I used to make regular backups to the whole folder, convenient enough using btrfs.
OpenTTD is more a strategic game,but it's great.
OpenRCT sadly requires the graphics of the original RCT2, so it's not really open source.
But also a favorite.
0AD is great. And whilst not a game really, FlightGear is the best you'll get for a FOSS flightsim. And really, for the prices that some X-Plane/MSFS planes and other addons go for, it's actually proper good.
Cataclysm: Dark Days Ahead, has a really strong community behind it. Be warned, it is an intensely deep simulation (as in dwarf fortress), that is often criticized for it's tediousness. But that gameplay element critique aside, it's a fantastic example of a community developped game.
Warzone 2100 is an excellent RTS that is open source. I've never played a game with a bigger and more complex skill tree. Has an interesting development history in that it was originally a Playstation game, but was completely open sourced once the company went under. It has been kept alive by fans ever since.
Forge, a Magic: The Gathering rules engine available both for Windows and Android. Various formats, good AI, offline and online play, and now even has a Shandalar-like mode. #MTG#MagicTheGathering#Forge#Shandalar
Colobot was made open source a while ago and is still great! The game assets (and original binaries) can also be downloaded for free from the dev's site.
I like re3, reVC and reLCS. These are reverse engineered versions of GTA 3, Vice City and Liberty City Stories with improvements. Take Two has thrown a strike on the main repository, but you can still find mirrors or builds in the internet.
Cataclysm: Dark Days Ahead, or if you like something a little less complex, Cataclysm: Bright Nights, are fantastic roguelike games. Proper traditional, turn based, tileset ones.
Imagine a mix of Fallout and The Walking Dead, that's what it's like. It's superb. The possibilities are endless

Looks like some very useful sites there. Thank you

I love the game, but absolutely hate the inability to freely save and load in a game where maps can last for hours.
Oof. That's a really major downside. Bummer.
Edit: just downloaded to see for myself. You seem to be able to save and load, at least in singleplayer on pc.

+1 for mindustry. Great game and works across all platforms.
Veloren is based on Cube World and it's an RPG with server builds and everything
Unciv is a decent Civilization clone

OpenRCT is an incredible achievement. The mods people make add so much more content.

Ive been playing a lot of MineClone2 which is a modpack for Minetest!
haven't used mineclone2, but i do want to echo minetest

Highly recommend. Easier to grasp than dwarf fortress, although finding community can be a bit hard since reddit shutdown
They also took the trouble and respect to make the game multi-language, unlike dwarf fortress.
A lot of good tips here, but you should have a look at Endless Sky! Really cool space game
https://github.com/endless-sky/endless-sky
Unciv if you enjoy sacrificing hours of your life :)
Are we talking about serious business civ 2 style, or something more relax like the 5th one ?
I believe it's based on Civ4 by default but can be modded to be more like 3 or 5
Unciv is great!
I'm surprised that no one mentioned super tux kart yet
I used to play Sauerbraten, a Quake-like FPS, way back in the day. Doesn't look like it's very active any more.
Oh, that's a name I haven't heard in a long time. I also used to play that years ago and I think even spent some time trying to create some maps.
Amnesia: The Dark Descent and Amnesia: A Machine for Pigs got open sourced if that counts.
Holy f— really? I used to love Amnesia back in the day. This is such a strange and unexpected, but really cool news!
OpenTTD is a pretty cool transportation and train building game
Shattered Pixel Dungeon Roguelike, very addctive :)
Make sure to help jumpstart the community here a [email protected]
Adding tales of maj'eyal to the roguelike list.
Havent seen endless sky mentioned here, it is an old school space trader sim (think scape velocity or a 2d freelancer)
If you enjoyed Zero-K, there is also Beyond All Reason in development and in playable alpha state

0 AD is a solid AOE2 clone
NetHack - Roguelike
Space Cadet Pinball - Decompilation of 3D Pinball for Windows – Space Cadet
The Battle for Wesnoth - Turn-based strategy game with a high fantasy theme
Mindustry - Sandbox tower-defense game
Minetest - Voxel game engine
Never knew about Mindustry, thanks !
I liked oolite and doomrl .
Neverball is my favorite. It's a Monkey ball clone.
Widelands is a good game in the style of Settlers 2.
(The later games in The Settlers series moved away from the distribution-network style of gameplay in S2; so Widelands how carries that torch.)
Colobot was made open source a while ago and is still great! The game assets (and original binaries) can also be downloaded for free from the dev's site.
Check out [email protected]. It’s my favorite open source game.
There’s also [email protected]. Awesome game!
Tux Racer is the OG.
Battle for westnoth !
And I can't remember right now the stealth game I used to play, it was the dark something, gonna search it later.
Quake and Doom.
I like re3, reVC and reLCS. These are reverse engineered versions of GTA 3, Vice City and Liberty City Stories with improvements. Take Two has thrown a strike on the main repository, but you can still find mirrors or builds in the internet.
Is there any mirrors with newer builds? I could only find the earlier releases when I looked.
I don't know, I compiled from source. If you use ArchLinux you can get
re3-git,revc-gitandrelcs-gitfrom AUR.I can recommend osu!lazer if you like rythm games, be careful not to get addicted though :P
For mobile games there is Shattered Pixel Dungeon, great time sink
Space Station 13 is great
DevilutionX (a port of Diablo and Hellfire) https://github.com/diasurgical/devilutionX
Cataclysm: Dark Days Ahead, or if you like something a little less complex, Cataclysm: Bright Nights, are fantastic roguelike games. Proper traditional, turn based, tileset ones.

Gonna try it!
I actually love IVAN, and I feel like it has been completely forgotten https://github.com/Attnam/ivan
