When After the End (a CK2 mod set in a 27th century North America centuries after an apocalyptic event reverted it to a medieval tech level) was ported to CK3, the devs decided to expand the map to include Greenland and South America, but quickly ran into an issue
Since CK3 was made to focus on Eurasia and parts of North Africa, the maps were hard coded to be longer than they were tall, which wouldn't work for the very vertical Americas unless they put a fuckload of ocean
Their solution was to just use a rotated map projection, and I really like it cause the simple act of rotating the map can introduce an aspect of unfamiliarity that further emphasises how different the post-apocalyptic setting is from the present
