It seems to me that the AI has some scripted or coded campaigning targets.
At least I noticed that England always attacks Bruges, Moors and Sicily are always attacking Cagliary, Kievan Rus are never attacking Caffa but Constantinople, Fatimids are always attacking Iraklion, Seljuks and Fatimids are turning on each other after KoJ is defeated, etc...
This makes the campaigns extremely predictable and boring in a way.
Don't know if others noticed this or its just coincidence, but I'd actually like to see France invading Spain instead of always turning east, England conquering the rest of the isles, or Scotland doing so instead of invading Norway, or see a muslim invasion of Europe instead of hick-hack in the Holy Land, or the Fatimids turning eastwards in Africa. Some variations.
So, does anyone know if that's easily changeable like written down in some .txt?
