My first question here is the issue of core provinces. (In EUIII)
Can you lose a core over time? I know you gain them over time (playing as ethiopia, I discovered this...), but I've never really seen a core go away...
I am curious, because I want to play a resurgant greek campaign as Morea, and I've noticed, playing as Ethiopia, neighboring Swahili gained cores on me via some random event...and they didn't go away, and I know that the Ottomans have cores on Athens and the Morea.
Second question would be...how on earth do you unify italy, when Roma is a requirement, and there is a penalty for catholic nations holding rome...
