Adding textures would probably be a really good feature.
wall: Brick walls, burnt bricks, rock, wood even (not for big city walls probably)
roof
ground/grass/field
The only thing to add is the texture vertex in the file and the corresponding texture link in the mtl file. I'm not too familiar with texture techniques, but probably the easiest would be to have a scale factor, to have a control of the appearance as it would appear on the buildings. Especially when working with textures of different resolutions. Since our triangles are quite big, I'm not sure it's a good idea though.
