Love those games too. Rimworld is the latest in my opinion. All the fun of Factorio and Dwarf Fortress plus a fairly good UI and space faring feel. Wasted/played too many hours. Make sure to use mods too. On steam.
Personally, I could never get into rimworld because I didn't know what to do. Never /really/ got into DF either, but despite the awful UI it seemed much more like something that could really suck you in, that was really engrossing and fun to play.
