Did a scan and didn't see a thread, so thought I would do a quick post! Feels like it would check a lot of DF player boxes.
"Shadow Empire is an immersive 4x game, putting players as leaders of small cities on random-generated planets, besieged by threats of all kind and forced to gather every imaginable natural resource in order to survive. Face the post-apocalypse, rebuild civilization and write your own destiny!"
Definitely has that mid-nineties feel. You start by generating your planet type including size, star type, rainfall, planetary age, atmosphere and then how badly it was blown up during the giant Galactic Republic civil war. One game you might be fighting over a barren, but mineral rich moon, and the next a poisonous jungle-world with 10 meter tall land squids.
You then have to work your city state up from Mad Max tech-level and rediscover all the old tech through conquest and Ruin-excavation. Next thing you know you have plasma guns, mechs and the occasional nuke.
Leans heavy on the wargame, so logistics and supply are king to keeping your army and people running smoothly. You also have to deal with your cabinet leaders who have a range of skills and stats from wizard to incompetent. The happier they are the more bonuses you will get, but if they're very unhappy they might try to rebel.

EDIT: And here's a {NEW!} link to SET-UP series by Dastactic w/ new aircraft. Very good for learning the game and a lot of the under-the-hood mechanics:
