Hrm...it does sound interesting. I remember playing something vaguely related in a sort of Roman Empire specific format...but that was a long while back and it was a good deal more character-specific rather than nation-specific or what have you. And I'm something of a Civilization nut. *shrugs*
If you got a decent number of people, I'd probably be up for trying it out...depending, I guess, on what sort of "NESing" would be done.
