Someone already told you this, but I want to elaborate
Dwarf Fortress was essentially what Rimworld was cloned from. I’ve been downvoted into oblivion by rimworld fans for such heresy, but it’s true.
For the longest time DF has been free, disgustingly ugly, and getting updates for like 20 years (think you can still download freeware version, but there’s a steam version now you can pay for. I bought it because it’s been a gem for YEARS and devs more than deserve my $20 or whatever it was).
Rimworld took the DF game, made it sci fi, and made it not absolute dogshit to look at.
You could always mod DF with icon packs that made it look a lot better but it was still pretty ugly.
The steam version of DF looks much, much better but it’s not quite as pretty as Rimworld still, I think.
Either way, if you got any time out of Rimworld and want something similar, Dwarf Fortress is your best choice. They’re both great and are IMO the best in class of whatever genre you’d call it.









I’m also way more into sci fi than fantasy. But IMO, DF is a much, much better game. I’ve never looked for a mod that does what you’re looking for but I wouldn’t be surprised if it exists, at least for the texture packs. I think it would be pretty challenging to make a mod that redid all the generated flare (like when your dwarves carve stuff up and there’s RNG of the scene they carve) but not impossible. I never cared about any of that crap so I never read it anyways, but lots of people love it.
