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?
I kind of wish that it’d support higher simulation rates and try to multithread at least some of the stuff (like, maybe they can have the pathfinding or temperature propagation span multiple cores or something, which has historically been a drag).
Animals and a few other things are now multithreaded, so it is something they’re working on.
