Here we got a sprawling city with a river, a pool and many buildings. This is a screenshot of an early city version - the later ones have a lot more detail (see below).

Here the PC encounters a river running through the city. In this early version there were no bridges (but see screenshots further down for bridge building efforts).

Yet another city with a river and a pool. This time the city also sports a city wall to be protected from invading forces.

Here we have a city with a ditch, a city wall, a drawbridge and actual city gates. And for the first time we see roads entering and leaving the city. Please note that most parts of the city now contain of mud tile - grass is more scarce.

This city has a river in the near vicinity of one of the city walls. Again nicely bridged and with a couple of lonely houses on the outer side of the river between the city wall and the river itself.

On this screenshot the PC is relaxing on a small lake in the city.

This city sports many roads, bridges and yet another beautiful river.

The ancient city depicted on this screenshot sports and "old town" encircled by yet another (second) city wall. Some mighty cities even can´have a system of ditches, walls and more.

This aged settlement also has a lot of detail: two wall rings (the outer one with a ditch), a park to the east, a lake to the south and no major roads - a clear indicator of the evolutionary growth of this city.

Here we have a minor dungeon. As far as I am concerned there are still too many tunnels being dug, but this will change as developement continues. Maps can be of arbitrary size so that a lot of variety is guaranteed.
