@Azimuth I think SZ 26 is expendable. I would recommend setting up the starting units in Europe before too long – if the map is expensive to print, then you could try to just print the European part. If the pieces don’t fit in, e.g., Poland then the map is not useful as anything other than artwork.
I applaud your creativity in choosing a polar projection, but as you are noticing, having a round map makes it harder to minimize the oceans, and harder to minimize the southern hemisphere.
The only actual mistake I see on the map is that Khantys-Mansis and Siberia should be swapped – in real life, Siberia borders the White / Arctic Sea, and Khantys does not.
I could nitpick some of the territory values; I think the Soviet Far East should be worth $2 for gameplay purposes, Iran and Australia should be worth more for historical purposes, and so on, but that’s just my pet peeves; that’s not really specific to your map.
It’s very pretty! I hope you continue to enjoy creating it.
