Just a bit of advice, when playing as the Axis do not attack Norway until after you've defeated Britain. As doing so will cause the British fleet to interfere, and losing one of your cruisers will make Operation Sea Lion virtually impossibe.

As the allies do not attempt the low countries gamble this is where you declare war on the low countries to either deny Germany the plunder points or actually conquer the low countries to establish a defenselive line on the Rhine. This will cause the Italians to join the war much quicker and the cost of defending on two fronts is not worth it.
