I heartily recommend trying out some CityBuilder servers. You claim a small town and provide it different types of cargo as it grows. It really tests your TTD skills, as you need to provide constant streams of cargo every month to keep the town growing.

There are probably several CityBuilder servers, but I mostly played on the BTPro[1] ones. Everyone starts at the same time and the goal is usually timeboxed to 3 hours, after which the server resets with a new map.

I haven't played the game for a few years, but these goal servers kept me hooked for months.
