According to the pictures, this looks like the old city builders from Impression Games.
Now is Nebuchadnezzar a "free" city builder or do we need to construct standardized housing blocks to control the service walkers?

Hi,

something between. There are walkers distributing goods and services to the houses but their paths are not randomized. They are fully under the players' control. It means that you have much more freedom in city layout because you walkers will always go where you want to.

That sounds like a good solution!
