The Planet Crafter. I started slowly playing it after Satisfactory and now I'm trying to finish before Rimworld's next DLC releases.

You are dropped in on a barren, inhospitable planet with finite resources strewn about its surface and slowly terraform it, restoring atmosphere, heat, and oxygen in tiers that reflect in the whole world/environment changing as you progress. Sustainability of your own survival is the most important factor, then reliable sources of resources, then exploration. It has such a simple premise but I've enjoyed it so much.

I have a few outposts around the map, but pic is my main base. It ain't much, but it's home.
