My mates and I love this map, it looks really sharp.
Although the map has lots of cliffs, it doesn't seem cramped, because you've increased the map area slightly to compensate.
Also, this map has more wood and food on it per person than the traditional Painted Desert map. It is up there with Saguenay for resource count (except for coin).
One problem though. We played a long game and it bogged down considerably because there's simply no way across the centre of the map. No way directly between the two bases. The problem is that the side passages are too narrow to maneuver in. There are some pathing issues in these gaps, that's how small they are. I took a couple pics to show you what I meant:
In each pic, the passage is exactly that many SMALL BOXES wide - the passage with a width of 2 is almost too narrow to wall up, let alone fortify. I put a castle there and had difficulty getting artillery to move out of the castle into the gap between its front and the narrows.
Is there a way you could code a larger gap between the cliff edges, so the passages are less blocky? Or maybe a second gap for each side, closer to the bases?
Otherwise the effect is spectacular, I love the extra level of cliffs above the outer ring, that really makes it look like a scene out of Star Wars or Indiana Jones.
