Hello guys, I am developing a map based off of this picture of Earth with land and water switched. http://i.imgur.com/O39zc.jpg
Any suggestions for land divisions and an alternate world history are welcome. Right now I am working on the North American Ocean and its surroundings.
Its hard to think about it, since the greeks and romans depended in their isolation and naval power, we can imagine a strong nomadic empire and a weak western culture.
Uk was never a great power since they also depended in their isolation and naval superiority.
If you do not want a super different universe, we can with Pre-ww1.
Lets start with the basics: uk,japan,spain and france are no longer great powers. Nomadic Tribes are stronger, and greeks no longer exist.
