* A Rural can also be converted to a Townsland or Stronghold and a Townsland can become a City.
* Likewise a City can become a Townsland and a Townsland or Stronghold can revert to Rural which can then become Badlands or Woodland.
* Actions could be introduced that players can use to change region types but some changes might be secondary in nature (overpopulate a Rural while not importing enough food will cause it to become Badlands for example)
So that a realm can increase its tax base by signing peace with everyone and micromanaging its regions? No thanks - if a realm wants more cities, it should have to grab them from its neighbour. I like that the map is fixed - it's the politics that is not fixed, and that's where the fun is.
