Blender is free (open source), runs on Windows, is available for download.
It has a Freestyle mode, which you can activate in the render settings.
Once activated, it will give outlines to objects.
If shadows are too realistic, you can turn them off in the lamp settings.
Making the lamp brighter does not necessarily affect the object, because it depends on the material of the object
Giving it a diffuse color of white in the material settings makes it even more black and white
Lastly, if those lines are too straight/computerized, you can change all kinds of settings, e.g. variation in thickness. You find those settings in the layer settings
You can even choose to include or exclude single lines:
- once you have modelled a city, you can use different cameras to get different views. You can pan and zoom etc.
- You could even render a background video by animating the camera.
- doing and learning all that can take a while.
