enhanced graphics & a curved world

First off, the enhanced graphics in LH are very impressive.  The game looks really good.

Second, as you play, visualize a slight curvature to the world map; and take notice of just how much more organic (and attractive) this makes it feel.

I believe this could effectively be achieved by simply post processing a slight fish-eye to the 3d world view / strategic map.  If possible, keeping the cloth map flat.  This one small enhancement would elevate the game, this work of art, to a masterpiece ; and is most likely much cheaper than actually curving the surface plane.
