Beautiful stuff here, the largest one is as good or better than the graphics on a state-of-the-art first person shooter, as far as still imagery goes, atleast in my opinion. Greedily, I hope that you will consider unleashing them upon the public in the form of a download we all can use
A nation built around the various horrors is a really good idea. Are you willing to give more detail as far as theme, basic units and commanders, etc? Even if we don't see your mod in the near-future, I'd still like to know more about it, if only to sate my curiosity.
