About This File
This was made by 'and, so it's called Andia. Lots of flat place for building, which is nice if you use roadtop mass transit of any sort. Features both coasts and mountains.
A greyscale image, region.ini, and config file are included. Use the config, or make your own to suit.
To install press Ctrl+Alt+Shift+R, browse to and select the greyscale image, then go do some chores while the game renders the map.
