I haven't availed myself of the save converter all that much, as it's too easy to create a megastate that can't be challenged since AE and Overex don't exist in CK2. That, and what always happens is that Spain gets balkanized by gavelkind, Portugal never forms, and France gets gobbled by HRE, so when the game is converted there is only one colonial power, England.

It boggles my mind that 11th century Byzantium is better able to incorporate an Indian conquest than 19th century Britain.
