When I was using JOSM tonight, the satellite imagery shown on my screen reminded me of something.

It reminded me of a simulation game I loved playing several years ago : SimCity 4.

JOSM and that game share many similarities. At first, both display satellite imagery. Then, you can draw residential, industrial, and commercial zones. You can place various amenities, draw different types of roads (from small paths to multilane highways), railways, power infrastructure, waste management facilities, airports, seaports, forests, orchards, etc..
