Since the days before Dragon Age, I have been looking for a game that would let you "enslave entire nations with necromancy." Bioware cut all the cool stuff out, and it wouldn't fit in an rpg as well as a tbs. So, I'm hoping that Elemental will let you do this because it's a Master of Magic spin-off.
If not, I'll mod it in. I hear the mod tools are supposed to be quite good.
