I need to watch some of the fame play videos that apparently are already out there, then, and decide if I wanna get this or not.
I’m thinking about my greatest CK2 playthrough to date – I started in the earliest 700s start date, as the Jewish count of Semien (a tiny county in Ethiopia). I took some land, swore fealty to the Christian King of Ethiopia, and eventually rose to the throne from within. I then swore fealty to the nearby Arab caliph (I forget which dynasty was in power then) and, through political machinations, installed myself as king of Ethiopia, Arabia, and Egypt – three of the strongest kingdoms in the caliphate. In the meantime the emperor had expanded to all of CK2’s Muslim world, from West Africa and Spain all the way to Afghanistan.
Despite being an enormously powerful vassal and an infidel, I kept good relations with the caliph by… well, let’s just say each time my own kingdom got a new heir, I would back the strongest son of the current caliph in a bid to take over the whole empire. That way the current emperor always liked my leader and put up with him.
Eventually I got powerful enough that I backed a son’s revolt – then declared independence from the revolting empire and founded an empire of my own (finally earning the Kingdom of David achievement, my goal for the run). The caliphate split between two powerful vassals of the old caliph, one in the East and one in North Africa. I went to wore with the western empire and conquered all the way to Mali and Spain; then the Mongols came and conquered the eastern half of the world, all the way to my borders in Mesopotamia.
I managed to hold the Mongols off for a time but it was a pyrrhic situation and my armies were depleted. Luckily before the Mongols could send another stack over they had a succession crisis. The new heir reunited his empire within a year but this gave me an opportunity to raise my favor with the off map Chinese emperor and call on his client state in Tibet to attack the Mongols for me. Somehow they won and the mongol empire fragmented, and I was able to push my lands out to the border with India.
There were some border skirmishes with the Byzantines but nothing I couldn’t handle – I backed an Armenian revolt against the Byzantines and then proved up the Armenians as a buffer with them.
Then came the Sunset Invasion. I held off the Aztecs in North Africa, but they took northern Spain and all of Britain from the locals. The game ended during a slow slog to take Europe from the Aztecs. Holy Fury came out and I abandoned that save.
Since then I tried to form the Persian empire while remaining Zoroastrian and independent the whole time, but have failed. Maybe I will try again in CK3.
