Imagine if the land were ocean and the ocean were land. As if in some parallel dimension everything was geographically backwards. This is what it might look like.
I used names from undersea ridges, basins, etc and other bodies of water for country and continent names. Some of them are pretty strange. The city names are made up though.
The cities start with what I hope is an appropriate number of neutral units.
No border modifiers.
No wrapping to the other side of the map. This is a flat world.
