I think the actual in-game name that we were thinking about giving it at one point was Castille and Aragon, could one of our history buff members remind we what happened with that?

I think the Ottomans will remain the Ottoman Turks as that was only their name with the Europeans anyway and it will be recognizable for everyone that knows about them.

I don;t know about the Poland one though...

Glad to hear you like the way it's looking!
