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.
