A lot of people around here have noticed that games in Iberia are a lot of fun. Plenty of Holy Wars. The French monster in your backyard. Lots of fighting and lots of challenge, with the possible payout of a big kingdom.
I just wanted to share my discovery of how much fun it is to play in Armenia because its pretty much the same thing but harder, with a little bit of the fun of playing the HRE thrown in.
Your stuck right in between Islam and the ERE. Plus you're a vassal and need to get independence to avoid the meddling emperor. And you have a free king title around if you can expand to get it.
You can Holy War your way to dominance if you're good. You can fight to expand inside the Empire. You can move up into Georgia. If you can form Armenia, you can then exercise all those tasty de jure claims in the eastern ERE. And eventually when the game starts to get dull the Mongols are coming. Good fun.
I played as the Duke of Mesopotamia, a one county Duchy with 5 counties to it with de jure claims for you (allthough the Muslims own two of them). You're right on the border with some smaller Islamic states so you can expand without directly taking on the Caliphates. But any power around that area would be good.
Try it. It's fun.
