Just to add to what I’d written previously: if anyone is interested in learning more about the New World Order map, I suggest this thread. Unfortunately, the picture only shows you the approximate center of the map; so you don’t get to see that Finland is included as its own nation with several separate territories to start with, and the opportunity to acquire a significant number of additional, neutral territories from Sweden and Norway. You also don’t get to see the (extensive) theater in North Africa, the Mediterranean, or the Middle East. (The Colonial French exist as their own nation; separate from that of France. That way when Paris falls, the Colonial French can continue collecting income and contributing to the Allied war effort.) The map also doesn’t give you the chance to see all of Turkey (with its important industrial complexes), the portion of the Soviet Union near Moscow and east of Moscow, or the eastern United States and eastern Canada. That map does, however, give you the chance to see the Romanian navy (all one transport of it!); the competing German and Soviet fleets in the Baltic, and the overall scale of the map. France, for example, is divided into 14 territories.
The discussion in the above-linked thread is a good introduction to the strategies associated with it.
