Rebirth of the World Map Game

What if in 1963, the ice caps melted, leading to world destruction and massive sunamies, but in 1994, the Ice caps stopted melting and grew back, becoming bigger and leading to new islands and landmasses.

Rules
The same rules apply for the map game except this one has NO ending so keep on editing

You can add new land masses if you want but the main thing that you should do right now is make the nations, because of the world disaster, nations disapeered and new ones must be created
