Xonotic. I even got a server in my region!

Some great games already on here, but wanted to share some love for VVVVVV which released its source a few years ago.
Puzzle
- Rocks'n'Diamonds - Digging for diamonds while avoiding boulders and enemies
- Enigma | github - Marble puzzles (and much more) inspired by the classic game Oxyd
- GNU Robbo - Solve rooms (puzzles) with your robot
Space

It's old but I always really liked WARSAW it was/is a quake3 port but with more cartoony outline graphics similar to Borderlands style.
I am a big fan of Neverball
Pokemon Emerald 😉
Warzone 2100. It reminds me of the older Command & Conquer games with a ton of upgrades and customization for your units.

Warzone 2100 is an RTS from 1999 that went open source at some point and can be played on just about anything. It's unit design functionality is really cool and I'm a sucker for post-apocalyptic worlds.
shattered pixel dungeon
+1. I probably spent 100s of hours on this game across commutes
Shapez is a fairly relaxing factory game. Pretty minimalistic style but easy to lose tons of time to if you aren't careful.
Only one that comes to mind is Lugaru. The creator had this weird legal battle where someone stole the game, ported it to iOS, and the thief claimed because it was open source he was allowed to sell it.
I like supertuxkart and minetest
Thanks for the Veloren recommendation, I liked Cube World, it just didn't work out well.
Simutrans. It's old but really good. It's really easy to lose 10h or so in it before you notice the time.
Doom :)
Aside from the other choices already mentioned (especially Doom stuff, FreeDoom ftw) any of the free games derived from the S.T.A.L.K.E.R. games and early builds, mostly Anomaly and Lost Alpha. There are also a few stabilized versions of the Build 1935 alpha out there which are worth playing and probably a bit more approachable for most people.
OpenTTD is a great open source clone of the transport tycoon game. And boohu is an awesome ASCII coffeebreak roguelike.
I'd say Pokemon Infinite Fusion. It's written in Rails and the artwork is done by the community
One of my absolute favorite games as a kid was Glest. Turns out it's open source and is now available as MegaGlest!
It takes a lot of inspiration from Warcraft but it has its charm and many of the races are quite unique in how you play them!
I used to play openarena (Q3a ish) a lot. And we had some group games of freeciv. I never got torcs to work well enough to play. That would have been great and simulation would be the perfect kind of "game" to free / open source. And countless hours of nethack on every platform I had (which was a few). Other roguelikes too. Ones that actually are like rogue, that is. Even rogue.
But all that was a long ago. Should maybe explore more.
