Er, I've got Crusader Kings 2. Those are my current arms in a game I started as Count of Kallipolis (in the Duchy of Thrace) in 1066. House name is "Lannister", cause I was lazy.
It's about 1370 now. Some time in the early 1200s, I inherited the Byzantine Empire, but was immediately thrown out by a vast pretender revolt (sucks to be a woman in CK2). I gained new footing in Tuscany, which was part of my demesne, and from there slowly conquered most of northern Italy and the Kingdom of Jerusalem. I swore fealty to the HRE, and some time later was elected Emperor and converted the HRE to Orthodoxism, though I was careful not to be re-elected -- can't compromise my Greekness. Some time later, I conquered what remained of Lannister-Sicily -- they had lost most of their Italian holdings to the Byzantine usurpers, but had considerable holdings in Africa. I took over half of Egypt to appoint an Orthodox patriarch of Alexandria. Sometime in between I forged an alliance of blood and Orthodox faith with the Ilkhanate, which had conquered all of Persia and its way to the Mediterranean, including Anatolia (up yours, usurper) (The Golden Horde on the other hand swallowed all Russia and Poland, but was beaten back by Scotland, which put them in the unique position of being a Shia state with no land connection through the Dar al-Islam to Mecca).
After some bribes, Byzantine vassals rose en masse to put me on the thrones of, in this order, Greece, Bulgaria and, eventually, Byzantium. Now, it's time to eradicate Islam in the Middle East and perhaps unite with the Ilkhanate.
I am currently playing as Basilissa Cersei I of the Byzantine Empire, daughter of King Jaime Alexandros III "the Restorer" of Italy. I am Empress of Byzantium, Queen of Italy, Sicily, Cyprus, Greece, Bulgaria, Jerusalem, Duchess of Tuscany, Countess of Constantinople, Defender of the Eastern Faith, rightful Holy Roman Empress, rightful Grand Khagana.
