I just come to end of a game with the duke of Turov : What a great game !
Firstly, I distributed my poorer lands to vassals, allowing to my heir a big block in the south, after married him to Adhelaid Salian, providing me the best european military force as ally. After married my other son to a croatian princess, I invaded the baltic tribes, and created the duchy of Lithuania. Then I created the duchy of Tver, and invaded a revolted TPM count. Having amassed 600g , I turned my eyes to Moldova, and invaded the Pechenegs lands.
At this point, things got complicated. The Couman king declared war on me and 15 000 tengrist took Kiev and other south cities, even with 10 000 germanic soldiers. Desesperated, I sent an assassin to Couman kings two times, and killed him. Effect : His vassals started to revolt, notably Crimea, and his army was reduced to 3000 soldiers. Thanks to Heinrich IV's army, I managed to make a white peace with him.
Please, Paradox, let me play sooner than 14th !!
