- revamp map of europe - western and eastern. better historacal shapes (no squers, trangles etc) and add few provinces. like rest of the world in art of war, it looks pretty
- an ability to recruit merc from other country if he allows to it by diplomatic action. create new merc ideas that improve their strength. I mean: do famous swiss, hessian etc merceneris

- new mechanic for Protestant
- give governments more depth, different mechanics. it was really big dissimilarity between feudal and absolutive monarchy, not just two or three bonuses. dutch rep., elective monarchy, factions for merchant rep. were fantastic addition.
- give missionarcies and colonist some actions. they are not used big time of the game
- rework military ideas. change their names and give to all military idea groups 4 land ideas, 3 naval ideas and bonus - land or naval - like quality has. for now colonial powers like castile, netherlands, england, portugal are not competitive to land powers. france takes offensive, castille takes exploration = no chance
