Adding to this:
- Veloren
- Cataclysm: Dark Days Ahead
- Mindustry
- The Dark Mod
- Oolite
- Flare: Empyrean Campaign
- Xonotic
- Unvanquished
- Frozen Bubble
- Nethack
Yes the interface is a mess. But it's ridiculously deep once you get into it.
Oh my goodness, yes! I spent hundreds of hours playing this as a kid. Angband too.
Tales of Maj'Eyal is a great little game if you're an rogue-like fan! I played so many hours of that game a few years back, it's seriously great!
My favorites:
- OpenTTD: Old transport tycoon game, but really fun especially in multiplayer
- Minetest: Minecraft-like voxel game engine, which means there a many different game modes
- Beyond All Reason: Great RTS, also great in online multiplayer or with some friends. (Disclaimer: Possible unfree licenses for artwork)
- Dwarf Fortress: not everyone’s cup of tea, but sometimes you just get stuck in it for hours on end
Dwarf Fortress is not open source. It is freeware. Parts of the game (some graphics stuff) has the code available but you have no license to distribute it.
Possible unfree licenses for artwork
I'd still consider the game open source, even if the art is copyrighted.
Dwarf Fortress
Is there an open source version? It's a great game (also try the steam edition if you check it out), but I thought it was closed-source.
Dwarf Fortress is not open source. You are correct.
BAR is so good!
Battle for Wesnoth
This one never gets the love it deserves. It's a fantastic turn based strategy game with multiple campaigns and storylines, multiplayer, and campaign design tools. It's an old project (started in 2003, IIRC), but it's still fantastic
Hedgewars
Basically, this is Worms but with adorable little hedgehogs instead of, well, worms. Single player is okay, and it has online multiplayer I guess, but the real fun (just like in Worms) is local multiplayer. Also, it has Portal Guns. There's really no downside to this one.

Re-volt io and RVGL
This one's a little iffy. Re-volt was a fantastic R / C racing game with bright graphics, fun tracks, excellent controls, and a killer soundtrack. For good or ill, it was put out by Acclaim, which self destructed in 2004. The Re-volt fan community, however, doesn't know the meaning of the word "quit."
Nowadays, you can join a lively community with regular online tournaments of the game. There's a new cross platform engine called RVGL (that's Re Volt Game Launcher), and metric tonnes of mods and fan content. You still need the original game's assets, though, which is where it's dicey; they're technically abandonware not open source, unless I'm mistaken.
Anyway, links!
Unciv
This project's aim is to be Civilization V, but with more abstract visuals, and, or course, free. In short, it's FreeCiv, but Civ V instead of II and a UI from the 2020s rather than the 80s. (Not throwing shade here; FreeCiv is an amazing project that is exactly what it wants to be!)
If that's not enough to keep ya' happy, I know a few more, but they've mostly been covered by other folks here.
Edit: formatting
Shattered Pixel Dungeon and other forks of Pixel Dungeon (but SPD is my fave).
Shattered Pixel Dungeon is a great game if you are into rogue-like games. Expect to die waaaay more than you win. There is a lot of depth and quite a few ways to solve the the puzzles and enemy encounters.
The developer has done an amazing job picking up where the original developer of Pixel Dungeon left off. Very consistent and solid updates and has plenty of plans for future updates which look interesting.
There are plenty of forks ranging from adjusting difficulty to overhauling the art or expanding the gameplay significantly. If you ever get bored, you can just try something new.
I've enjoyed the growth of this game over the years after the development of the original game stopped.
Yes, I love that the dev is so engaged. He also started up a community here for Pixel Dungeon as well.
I'm glad Shattered csme along. I didn't care for item degradation that the original dev of PD built in towards the end. Shattered forked at just the right time.
Sprouted PD is fun if you enjoy grinding.
OpenTTD. IMO mindustry, for example, is better but it's still worth to try OpenTTD
Endless Sky.
It's an open world 2D spacefaring game, with a good core story and more being added by the surprisingly-active dev community.
Not without its flaws, but anyway I think it's a fantastic game in its own right. And it's both "finishable" and under continued development & expansion.
It’s surprisingly well written. Both major story arcs had me on the edge of my seat.
Endless Sky is great. It was inspired by the old Escape Velocity games by Ambrosia Software.
osu! is an amazing rhythm game. Try osu!lazer, it's the new client: https://osu.ppy.sh/home/download
I also like Pioneers and Endless Sky, both space sims.
This might not count, but both Lichess, a chess website, and OGS, a Go website are open source.
There is also Mindustry, but I haven't played it.
Not only is Endlessly open source, it has been crowd developed for years and years. It's still actively adding user content (stories, outfits, ships, races, etc) and has the only actually functional launcher I've ever seen (like if you want to play a stable release, or play in your own sandbox development area, etc). It's really great community of folks.
Really nice recommendation, thank you!
MineClone2 is addictive. All that Minecraft style fun, but free and open source. It's pretty comprehensive and solid for the most part.
How does it differ from Minetest?
Minetest is the engine and Mineclone2 is a game/mod for it.
Minetest is the engine, MineClone2 is the game. Minetest game has a default game (Minetest game), which has no mobs or anything. It's dull without mods. MineClone2 is recreation of Minecraft on Minetest, but with some differences. For example, you can use a burger to lure villagers. It's great fun and worth a try.
Naev - an open world space exploration game. Cruise the galaxy as a bounty hunter, work as a freighter, enlist in the military, or become a pirate! Lots of ship customization and a huge map with lots of factions.
My PC always has 3 games installed, and depending on the distro I'm currently on they may have come directly from the default repos:
- Battle for Wesnoth
- Warzone 2100
- OpenRCT2
I have lost count of how hours I have in all 3.
Xonotic, if you like very fast paced shooters.
People like giving recommendations like Super Tux Kart that haven’t aged well and don’t play well.
What's the issue with SuperTuxKart? I thought that it was great fun when I played it.
It's just not very good compared to any other kart game. Aside from the fact that it's very dated, the driving is slow, the levels are wide and uninspired, the racing itself is very simple. SRB2Kart is another open source karting game and it's sooooo much better.
For a game currently still maintained, it seriously didn't age well in all departments especially animations, sound design and character models.
Beyond All Reason if you're looking for an RTS similar to Supreme Commander. I haven't tried playing it in a few years though. I'm sure it's gotten some updates since then.
Great game, although someone recently told me not all graphics were licensed free licenses.
Which of these are available on Android?
I have F-droid, and Ive installed Mindustry and Open Transport Tycoon Deluxe.
Mindustry is great for wasting time.
Battle For Wesnoth is on android, the controls are kinda wonky but it's not bad.
SuperTuxKart and OpenTTD.
I had fun playing Dink Smallwood (I think the Dink Smallwood HD Version on Android). You run around, solve tasks, and work your way through the story.
It is, as you described, not actually great, but great in a sense that you can have much fun with it. I especially liked the humor.
CDDA and Shatered Pixel Dungeon arey favorites.
Space Station 13 is great
ScummVM supports many many games. Some people might think it's an emulator, but it's actually a collection of reverse engineered game engines.
eDuke32 and other Build Engine source ports
