I love Endless Sky, it’s honestly one of my favorite games! I have a pack of cool SciFi art that I found on Nexus and I’ve been slowly replacing the stock photos for my personal game. I’m also a sucker for TeeWorlds, it is delightfully infuriating and hillarious to play. I know that’s baby’s first FOSS games but I’m new to open source games. That’s why I want to hear your recommendations and see what are some other good ones out there.
I like simutrans a lot (maybe the most elaborated TTD-like transport game), and I am trying to learn freeciv, but it is a bit “technical”. I also like minetest, I have constructed a lot of big houses, the only FOSS game where you can cook a lot of recipes.
