This is where we are at, at the moment.
Couple of comments. First, I'll be applying a decal to the ground of all buildings (except those built with the 4-way road decal). So the ground will appear green, not bright brown. In previous screenshots I was using a terrain mod but it affects all kingdom cities and it doesn't look good for other factions. Edit: Actually, I'm not sure about this - I might use the terrain fix instead.
Secondly, the buildings in the back aren't actually as "big" as they appear, they just happen to be standing on a slope. Third... FPS drain actually not bad at all - I will probably skip doing a low-fps version. Fourth... I still haven't done the terrain adjustments where its needed. Fifth... the wall turned out boring with almost no trees on the outside, I'll add that.

Also, I want to reduce the House design a bit. It's too large. Comments?
The XML for the buildings and the tech trees are now 100% done. All that's left in the XML framework is armor, weapons and other equipment.
