It was too hot to add any cool features, the only meaningful progress I could make was splitting countries into smaller provinces. I don't enjoy asset work, too bad you can't make a game without assets.
I hit a wall with Natural Earth dataset as it only shows level 1 administrative divisions. For Voltaire's nightmare I need more granular subdivisions, so I had to change the map generator — now I can use geometries from multiple datasets. Modern, historical, fantasy — whatever comes in a shapefile will work. Here I'm using geoBoundaries DEU ADM2 for Germany with everything else still using Natural Earth geometries.
I want to tinker with shaders a bit more before I start advertising the game, it doesn't look like I want yet, but I noticed that I already have at least one player.
