Crusader Kings II, would highly recommend it for anyone who likes historical strategy games. In my current game I've been playing as the Norman Duke(s) of Apulia (the descendants of Robert Guiscard) and married into Greek Orthodoxy, finally converted, then swore fealty to Byzantium, and was recently crowned King of Sicily after driving the Moslems out. Unfortunately the current Byzantine Basileus has turned into a complete tyrant and has been centralizing authority left and right, making me regret my decision to make myself a vassal of the Empire.
How's it compare to Crusader Kings? I enjoyed the first one, but at times it just seemed to lack...something. What are some improvements and drawbacks in your opinion, when compared to the first?
CK2 improves significantly on UI, graphics, and AI, and is much more polished than the original. People are still singing its praises on the forum, and to give an even better idea, it has a 10% higher rating on Megacritic. Icing on the cake, they're planning on adding more major features for free in addition to DLC. I'm really hoping for one that renovates Byzantium or Eastern Europe, as well as the Papacy.
Drawbacks... well, there aren't many that comes to mind. I guess some of the new features, such as mayors or the education system, could have been better implemented. But I have high hopes for future additions and it's a solid game as-is.
EDIT: I just remembered, I was driven crazy by the fact there was no difference in portrait appearance between Catholic and Orthodox bishops. Luckily I've installed a mod to fix that (just a sample of the vestments, in-game they have full facial hair):
