The generator focuses on the outline of the buildings that coat the city, so it’s not very detailed. It will give you a random cityscape at first, but you can edit it quite a bit. Watabou’s generator is a bit different from the others. Donjon also has a second map generator that lets you put a bit of extra stuff, like names, on top of the original map you created. You can change the coloring style of the map, too. It mostly lets you build a world map, with tools for editing the water, ice and land quantities. One of its tools is a simple fractal world generator that isn’t too detailed, but it’s quite functional. With it, you can create new names, storylines, and calendars, among other things. Donjon is a free website with several generators on its main page.
