Rules are the same as usual except:
1. The game starts in Winter 2000. Each power builds 5 units in the sc's of his choice (out of his colored centers). These are the sc's available for building for the rest of the game.
2. 'S' denotes a strait. Artilleries may cross straits without a convoy. In addition, if both centers on either side of a strait are occupied, a fleet wishing to go through the strait must have permission of one of the occupying units (A Ethiopia Permit F Red Sea - Arabian Sea). A unit is considered to occupy a center if it stays in or moves to that center.
