Well, for Russia, you can play as Peter instead of Catherine. As for England, I am sure Winston Churchill would go nicely in the expansion, and maybe King Richard the Lionheart as well. What do you guys think of Braveheart as the leader of Scotland? The traits would be agressive and expansive, with woad warrior as the UU (strength 7 swordsman, 25% hill defense since they are highlanders), and starting tech of animal husbandry and agriculture.
