Thank you @Buck2005 ! Good thoughts here. For the world map that you have played, was it the gigantic one used in the Imperialism scenario, or otherwise?
For the North Sea Passage map idea, I was thinking of trying to make a flat map that operates in that domain, but does not incorporate the whole world. What are your thoughts on that? The excessively large landmasses of North America and Siberia, in this case, become the new world according to the post-apocalypse, and Greenland becomes a more temperate biome. Something like below, but I could narrow it even further.
