SimCity 4 did nothing to change this formula but continued its logical progression.
It lets you build enormous cities, and then trade resources with the neighbouring city you built previously.
Mods are why I’m confident calling SimCity 4 the best citybuilder of all time.

More specifically, it’s thanks to the internet Addon Mod.
The SimCity 4 Deluxe Edition (including the Rush Hour expansion, also released 2003) ison SteamandGOG.
