I like the idea of ships, space stations, etc. that are so large they have they their own self-sustaining ecosystem and economy. A system so complex that it’s practically a living organism, with humans acting like cells to maintain something beyond their comprehension.
I love the systems-level thinking that goes into these things so the harder the Sci-do the better.
I think Warhammer 40k often has settings like this, but the tone is a little too negative and fatalistic for me. I’m ok with dark and somber, as long as there’s even a shred of hope somewhere.
