Thrive is an evolutionary survival game. Similar to Spore, you start as a single-cell microbe. You gather nutrients, evade dangers, and evolve adaptations. Eventually, you can progress to the multicellular stage, then macroscopic, etc. up to spacefaring. Currently everything after multicellular is placeholder, but the cellular gameplay is fun and has enough viable strategies to make replaying interesting. https://github.com/Revolutionary-Games/Thrive
Cataclysm DDA is a zombie-survival rogue-like simulation game. You start as a single survivor and need to scavenge for food, shelter, and protection. If you like games that focus on system/simulation complexity over visuals (e.g. dwarf fortress) I’d recommend this one. For example, the vehicle system allows you to build custom vehicles, which can be anything from a dinky wooden bicycle to a monstrous RV-turned deathdozer+mobile base-on-wheels. https://github.com/CleverRaven/Cataclysm-DDA
Endless Sky looks cool. Definitely going to give it a try.
My two favorite open source games are Thrive and Cataclysm DDA
