I am playing MyMap-AGCEEP. This has got to be the most f-ed up Iberia I've ever seen.
There were rebels everywhere, so first all of Portugal except Lisabon became Spanish. Then Granada rebelled from Spain, and Spain had rebellions everwhere. Now, a few years later Iberia looks like this:
A few years later, France annexed the Hugenots, and another province rebelled to Portugal. Also, a vicious cycle has begun where Catalonia will rebel and become independent once every ten years or so, just to be annexed by Spain or France, who are allied.
Then Catalonia acutally won a war and gained a province from Spain, and allied with England and Portugal. I don't have a screenshot of this, but if Spain-France attacks Catalonia, it should be a fairly interesting war against England-Portugal-Catalonia.
Granada has just begun to reclaim south Iberia and converting those pesky catholics.
From the same game: religious chaos.
Protestant Austria
Protestant Lithuania
Protestant Brandenburg... who is also emperor.
In fact, only France, Spain and Portugal are still catholics as of 1620 (the screens are from the 1500s). The papal states were attacked by Naples and Venice in the late 1400s, resulting in Venice taking all provinces except for Rome, and after that Naples annexed the pope.
I am playing the Byzantines, trying to reclaim my empire. It isn't easy, because the Ottomans managed to secure Egypt before I could completely take them out.
EDIT: Also, a little montage of two of the oddest CoTs I've seen yet:
Greenland is Swedish. =)
