Friday Night Funkin!
VintageStory is kinda open source, and far more polished than any other minecraft clone.
People have already said a couple of my favorites ( Super Tux Kart and Mindustry ), but I’d like to bring up one almost nobody talks about: Me And My Shadow
It’s a 2D puzzle platformer where you control one person normally but then press space to record movement for your shadow character. Last time I tried downloading and playing it on Linux using the appimage on Sourceforge, pretty sure it didn’t work because it might need an old glibc that has features that might not exist in newer versions.
This post reminded me of the game, so I’ll download and see if I can run it on my desktop. Really feel like playing it now.
Edit:
I am too dumb to figure out how to make it work. Best I get is nothing. Not even a pop-up saying I need something else to make it work. So, I guess plating the windows release through WINE is the best I’d be able to do.
I still play 0AD every now and then
Pixel dungeon.
Super Tux Kart
I don’t see this one mentioned often, but Frogatto & Friends is a lot of fun if you like platformers with an old-school aesthetic. I keep it on my Steamdeck to play a few levels every now and then, it’s a smooth game with a nice feeling to the controls.

The source is here.
Mineclonia has like 95% of the features of Minecraft but is way better because you don’t need a Microsoft account, plus modding is easier.
Also awesome:
I had only heard of minetest. How does it compare?
An unofficial Minecraft-like game for luanti
Luanti is what Minetest was renamed to so it basically is Minetest
Luanti (formerly Minetest) is a little weird, in that it’s really just meant to be the game engine, not the full game. Mineclonia is basically a mod that adds back in all the extra mobs and whatnot Minecraft has.
What’s different between Mineclonia and Voxelibre?
Adding OpenRCT2, but I think most anyone who knows of OpenTTD knows of that.
Also, I’m not sure you can count OpenRCT2 as fully open source, as it still requires the closed-source game files to run – they haven’t replaced all the game assets yet.
(That said, it’s still fantastic and by far the best way to play RollerCoaster Tycoon.)
Shattered Pixel Dungeon. The dev is even active on Lemmy! !pixeldungeon@lemmy.world
Not sure if it’s my favorite, but openttd was already mentioned.
It’s such a fun game, especially after you beat a campaign level. I love that part purely for the freedom it provides after a hard fought battle.
beyond all reason
Isn’t Doom open source now? Does that count?
It is and it does.
SuperTux! 🐧
