Hi, love this map, best Earth map I have played so far. If you were looking for insight on what maybe to add or change I have a few thoughts:

So Russia starts off as St Petersburgh which makes sense so they can access the ocean but the only issue is that it pushes on the Scandinavian civs who already do not have much land and leads Russia to expand north which allows other civs to take land the AI should have taken.

Also, the British Isles should be made a few tiles larger because the Cliffs of Dover cannot be built on and in a game where districts are everything this leaves England at a huge disadvantage.

Also, Florida should be made one tile longer, and Italy should be made a bit bigger with the volcano wonder pushed down a tile or two so Rome is not at a huge disadvantage.

Also maybe add an option for where the new world is covered in resources for players who wanna play with no civs in the new world, so then this would encourage the AI and players to colonize.

Those were some thoughts I had! Overall, its a sick map, well done!
