Ah your are right, i was only thinking about 90° and 45° like in AOE . If we could build walls and fences like a straight line between any two tiles that would be awesome 
I hope something like this is possible, without any fixed angles.
Yeah i like your idea, but maybe it’s a little too complex to be put in before release.
Maybe there will be a advanced gardening dlc after release 
I would buy it!
But I would love a little tweak to the desirability system. That building green spaces in cities would be a bit more rewarding
