Seen it in my game too, Aq Qoyunlu decided to take on everyone to the north and east at the same time, right on the second day just after all the alliances/rivals formed.
Also, by 1461:
Aragon has eaten most of Castile already
England attacked France and took two provinces
Provence attacked France, and won a province off them
Scotland ate Tyrone
Serbia ate Bosnia
Bohemia ate Silesia
Genoa declared on Venice and is obviously losing that
Timurids took half of Uzbek
Sweden is independent and took a couple of Norway's provinces
Muscovy is about to take a chunk (if not all) out of Kazan
Morocco ate Tlemcen
There might be more too that I've missed, TI and my knowledge of the HRE is limited.
I don't mind an aggressive AI, but so much land is changing hands so fast, at this rate it could just be a few big blobs left by the 18th Century.
