Good stuff. Very well-played, it seems. Especially for your limited experience in DW.
However, keep 2 things in mind:
1.If a province that you are sieging has low morale(Like in the image with the highlanders), just assault the province to quickly gain control of the fort. Keep in mind that assaulting is very handy, especially later on when you have higher morale.
*That's assuming you didn't assault the fort, if you did, then never mind*
2.Watch that infamy limit. Unlike IN, when you go above the infamy limit, there are actual bad side effects. These include: Massive rebellions, war exhaustion increases, many wars, etc.
Taking provinces with a casus belli that isnt reconquest, conquest, holy war, etc are 4 infamy each. Reconquest brings it down to 0 infamy per province(!), conquest, holy war, and excommunication 1 infamy, and others 2 or 3. Try to take provinces only when you have a decent casus belli, or if you have infamy to spare. Keep it up!
Overall, this update seemed a lot better than the other one. Keep them coming!
