So I have been playing Crusader Kings 2. I had to deal with a traitor vassal. I won that and a little while after Arabic guys were asking to be stewards and all. I was wondering where do these guys come from and then I have my hands on an army of 80000 in Bakh(Far to the east). I don't rule there. Was it the crazy marriages I was arranging with no idea of what I was doing or a bug of some kind, I don't know. But 80000 Jesus, Mohammed, Moses and nothingness. I was only able to raise to 8000 before.
Crusader Kings 2 is a crazy game. In terms of creating fun stories for you to tell, it's one of the best ever made. It helps that there's no real end goal other than to try to gather prestige and piety -- you're just playing the game to see what kind of crazy stuff happens.
My strategy is typically to begin with a weak Duke (I find it too easy and uninteresting to
begin with a ruler) and then to try marrying myself or my male heir to a female heir of a kingdom that has agnatic-cognatic succession. Then their son inherits the kingdom. Then that son marries another woman ruler, and their kid inherits
both kingdoms, and so on. It's worked pretty well for me so far, but it leads to some interesting complications. At one point my son was 8 years old and had inherited the Kingdom of Aragon from my first wife, while I was King of Navarra. I was his heir and he was mine. Then I had a second son by the Sicilian queen. At that point, it seemed pretty clear that the best strategic decision was to assassinate my older son, which is what I did. That way my younger son would inherit three kingdoms, instead of having them get split up, two for one son and a single kingdom for the other. Gotta love a game that makes you assassinate your kid.
In my current game things are going pretty well, I'm the Byzantine emperor and have about a dozen kingdoms under my belt, half of which I married into, and the other half of which I created. But I've got problems. The Holy Romans are breathing down my neck from the west, Muslim kingdoms are attacking on the south and east, my Russian subjects are constantly revolting, and worst of all, the Mongol Horde is bearing down on me. The Mongols are programmed to take over most of eastern Europe (right where I am) sometime in the middle of the 1200s, just like real life. They show up with like 150,000 troops and just wreck everything.
Probably the funniest thing that's happened so far in my game has to do with religion. When I managed to marry into the Byzantine Empire, I offered vassalization to my wife (I was the king of Croatia), so that I could convert to my ruler's religion. Basically, I wanted to educate my son myself, but I
didn't want him to be Catholic, because he would have zealot vassals who hated him because he wasn't Orthodox. But he turned out Catholic
anyway. When my wife died, I worried there would be revolts that he couldn't handle as the new emperor. But as it turns out, my son handled himself fine while I was still playing his father, and started
converting the entire Byzantine Empire to Catholicism, and at this point in my game they're virtually all Catholic now, with the exception of the Russians. You really can't make this crap up. At least the Holy Romans like me better now.
