The fukkery thar can happen in this game is
In my latest efforts to unite Africa, the byzantines got so salty about taking North Africa, they spent generations in debit trying to win it back. The mongrols ran train on them and they would still send their armies to challenge mine.
In another playthrough, I had my Igbo princess marry some Viking rebel leader with goat stats. Cac dies in a failed revolt, shortly after getting her pregnant. I write her off because she goes to court in his sister's cousins in the far North where I can't interact. 100 years later, and theres viking mulattos with Igbo names raiding England
. Turns out the marriage I set up opened the Rus up to some distant cousins. They took over because I leveled up the Igbo culture to be top 3 in the world and I made myself a God king, head of religion which gave my bloodline divine blood clout. Them cacs had no chance. They were heretics though so I had to put them down once finally crossed paths.
I'm thinking about doing a lover boy playthrough. Getting kings wives pregnant and blackmailing everyone involved, then setting up puppet kingdoms
