Would this scenario idea work?
Five player game.
One player is the Superpower.
The other four players represent the 3rd World.
The Superpower starts the game.
He takes three years of turns (36); known as the "buildup" (he could probably accomplish this in a day or two).
He also sets each of the 3rd World nations to build only supplies during the "buildup". (The 3rd World players would not take turns during the "buildup".)
The Superpower cannot declare war on any 3rd World nations during the "buildup".
After the "buildup", play begins as normal.
3rd World nations can ally or fight each other.
3rd World nations can declare war on the Superpower at any time, but he cannot declare war on them until six years have passed (three years after the "buildup").
The Superpower can have one 3rd World client (ally), but can't give him territory or units.
The 3rd World can win as a group.
The Superpower can go for the single win, or a double win with his client.
Would probably have to tweek the game for play balance.
Spy network: Since the Superpower set up the game and set all the 3rd World nations to build only supplies during the "buildup", he will know their passwords. Any time during the game the Superpower is allowed to pull any 3rd World nation turn from the DropBox, open it, and look around.
