Try SimCity 4 with NAM[1]. It adds quite a lot of features to bring it up to nearly the level of Cities: Skylines without any of the stuff you might not like about that game. Essentially NAM enables unreleased transportation simulation rules and adds more building pieces, making it a lot more realistic (in both how sims travel and how you design cities).

I prefer it to Cities: Skylines but it's extremely buggy and you'll probably face a ton of crashes (and lose data in the process).

Someone needs to make a FOSS clone of SimCity 4 or 3000. I'm not the only simcity fan that dislikes Skylines.
