Yeah, Navarra has very nice sliders. I kind of defeated myself when I allowed it to revolt away from Castille.
I am going to play the last 20 years in three different ways.
1) Admin, where I concentrate on a fair race.
2) Diplomacy, where I try to ally with a European country and get them to annex Navarra in a war.
3) War, I am going to declare war outright, and annex Navarra myself and on sell it. Might also fight Milan to slow them down a bit.
