Dominions 5 MP for me. In between that, I began a CK2 game myself last weekend as the Duke of Toulouse, 1066. William the Conqueror succeeded in defeating the Anglo-Saxons, but ultimately lost to Harald Hardrada, which means "England" along with Normandy is under the control of the Norse. Good times.
Things were stable, until I started banging my brother's wife, got her pregnant twice, and got caught (oops). Had some legitimate twins from the actual wife right before dying of smallpox, and now having some succession crises with a 3 yr old Duke and a regency in control. Whilst the King of France is off fighting a holy war in Muslim Spain, Moors are pillaging Northern France. Oh yeah, the former wife, who is my Duke's mom, is now queen of France.
Love this game.
