Now you can take the pictures that @hushush drew and reflect them to make the fourth view, so in reality, you should only need 2 images to be able to turn a building all four ways. The only downside that I see to this would be if bast decided to make light-up night versions of a building that could be turned four ways, because he would need four images for each building then, and that would take a very long time to do every single building.
if all buildings will have multiple orientations does that open up the possibility of map rotation?
If you guys need some help with the artistry I might be able to help I am fairly decent at drawing being architecture student. I would love to help create 4 different views for some of the buildings.
For the Crimson fleet grows closer.
