Something like this... A "main" village that gives access to other small neighborhoods.

The idea is to have a central city where most of the population is located, and at the end of the main road, there are small intersections that lead to other neighborhoods.

The problem is that the city depends on buses (I took a rural bus pack) and trains (older bus pack) without the use of transport via ships, subways, trolleybuses, etc....

It's a bit of a challenge in which it would be frozen in time, without the use of modern means, and also developing the city without large buildings but rather in the interior of a country.

Some challenges that I included in the challenge are that the city must have at least 50% of its income from farms (Not counting periods when it produces less). Another challenge is that the city has to have at least 30 thousand population without the use of buildings, and without creating a very large neighborhood, but rather one far from the other. The city is obliged to have good management in the developed neighborhood (Like the image above), ensuring that it is neither too big nor too small, and that it is a "main destination" for citizens. The neighborhoods (ALL, without exceptions) cannot have a completely complete subdivision. (As above)...

That's it in short... Could you give me tips on what I can do and how to plan?

Byee!!!
