I'd love to be able to divide the map into regions/countries. However, I'd like to draw lines instead of rectangles... (or making multiple rectangles 1 region).
In a normal Simutrans game, this could be optional and is purely visual. and if you could script things for regions in scenarios this would be a huge +1! (as I'm planning a scenario with countries as well
I know borders has been requested before, but I hope this gets reconsideration as this doesn't change gameplay in 'sandbox' mode, but opens up many possibilities for scenarios.
