I was building a new map, a possible future demo.sve candidate I suppose, and I noticed, our "quarries" are all set up to require large flat areas. Whereas you really want to put them in mountainous terrain.
Is it possible to code them to require flat but diagonal tile arrays instead?
British quarries were often cut into mountainous hillsides, e.g. at Llanberis
Perhaps therefore our quarry industry should do the same.

It would probably be possible in principle to do this, but would require a gargantuan amount of work, as it would break some quite fundamental assumptions about how buildings interact with land in the game that are made in lots of different places in the code that are hard to track down.
I am afraid that this sort of thing will have to be filed in the (very long) "maybe one day" list for the time being as there are lots of things that are fundamental to game balance that have been outstanding for years.
