As Cities Skylines II still isn’t worth it (the sub has a regular thread about that, in summary: no it’s not: https://old.reddit.com/r/CitiesSkylines/comments/1ch6lup/is_cities_skylines_ii_worth_it_megathread/) which games scratch your city building itch?
well, rimworld does have a focus on (micro)management and strategy!
if your pawns are constantly down due to raiders, then you need better defenses! …or tame a herd of animals and release those at your enemies! (rhinos work very well for this!)
there are tons of little optimizations you can make to efficiently run a colony. for example, social fights: you can keep those from happening by keeping the problematic pawns in different areas! or removing one or both of their tongues! or sending one on basically permanent caravan missions! etc., etc.
this kind of deep strategizing, combined with the random bullshit the game throws at you, is mostly why people love rimworld!
and mods… definitely get mods! that’s where the game reeeaaally shines!
