What types of terrain will pcities be buildable on/limited from?
Specifically:
* any water rooms?
* swamp?
* paths?
* roads?
* ruins?
* shallows?
* beach?
Particularly, there are a number of places where a road deadends right into
the sea...will people be able to place a city block on that square at the edge
between the sea and the road, overwriting the end of the road?
For the other terrain, i can see reasons for and for not allowing cities on
those terrains...

P.S. Players: I've set up one set of maps for some players to help place
cities in the outworld...let me know if you'd like me to set up a custom copy
to help you place your own city. (for a fee of course)...and if you want to
roll your own, I can provide you access the tools as well...
