No, this post has nothing to do with playing the game differently at Christmas…
Many players have said one turn in Axis and Allies represents about 3 months in the war (there are some problems with that, but just assume for now that it’s true).
So then, each turn corresponds roughly to one season. Global 1940 begins in June 1940, so let’s say turn 1 represents Summer 1940. That means turn 3 is Winter 1940-1941.
Now, in real life, winter caused a lot of problems in the northern Hemisphere. Planes were grounded, ports were closed due to sea ice, and troop advanced stalled due to blizzards.
So, how about every four turns, starting on the third turn, winter sets in. Troop movement is reduced by one for ground units in the northern third of the Global board (for those using printed maps, this would be every territory with at least a part above the top of SZ 103), and sea units in any sea zone touching the top of the board cannot move at all.
This would probably favor the Allies, since it slows down the German advance towards Moscow, but everyone says Axis has the advantage anyways, and this rule affects the Allies too, so I don’t think it will be a problem.
I tried to think of rules for the other seasons, but couldn’t come up with anything good, but if you have an idea please post it.
