Thank you for the answer. It prompted me to gen a world without
pois, to see the how it lays out now. I haven't done that in a long time,
just played. The interesting thing that I learned, was the dependency
on wilderness pois. I hit F1 to see the process, applying wilderness
pois was near to last, and without them it stopped processing.
It does not need the city and rural pois, it will still generate the
city grid layout without them. Does that mean with this system, that
I can reset all of the pois to wilderness, and generate a complete
map using the random wilderness rule layout? Is there a way to generate
the world with out the poi cluster grids?
Edit: I just thought of something because of your post and then reading
@Space4Ace post above. Since the courtyard perimeters all have corners
can, a block be created, called a keystone block. Placed at the 4 corners,
that has a distance requirement for streets and roads, kind of like the avoid
mouse script use to do?
