Hey there,
I enjoy Linux gaming via WINE/Proton, but I often wonder about Linux-native FOSS games. You often see brilliant titles like 0AD and Mindustry mentioned, but there are also some unspoken gems in the “genre” like Minetest and it makes me wonder what other FOSS games are out there, that people just don’t talk about much? I’m looking to discover and play more of these titles.
Here is also a website where you can see if there is an open-source port to non-open-source games or an alternative that e.g. tries something of its own / builds on the game principle. As an example, Minecraft is listed as “clone” Minetest, MineClone2 (now called VoxeLibre), ManicDigger and more.
