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?
Along with your not city builder but somewhat has the same feeling as one, I’d add Factorio. The way things link together, and you essentially build roads/trains for supplies, gives a similar experience. I think there’s also a mod that adds people you have to take care of and other City-builder mechanics.
