Re: Region Modding: Roads
Somewhere - though I´m not certain where - it has been stated that roads are generated automatically between two cities. They better be, for there´s no such thing as a map_roads in the worldmap directory, but considering I´ve been playing mods which extended the world map and had roads in the new regions, I´d take it as a save guess that they´re generated automatically.
Re: Region Modding: Roads
Yep. The auto-generator sometimes works a bit oddly, though, particularly where it has obstacles to work around.
