We have developed a way to play games on maps of Slovenian cities. With the help of multiple open source government databases and powerful Sinergise tools, we create height, vegetation and water images. By bundling all of this together, we can play the game Cities Skyline! A python bot takes care of generating vegetation, whereas the height map gets automatically imported. We have also developed a nodejs solution to have a lovely dashboard where the generated maps will be hosted for users to access.
