I just finished the mod the combat-way, which was surprisingly easy using a small legion of mounted swordsmen. Those don't stay mounted very long sadly enough, because the villages are full of obstacles (trees, fields that don't disappear in winter, huts, etc) that the AI deems perfect places to dismount and tie their horses up. The peasant numbers aren't always correct either, and the thieves' guild even has spies handing out negative peasant numbers.
Some things that would make the mod more of a challenge/more awesome: - longer building times (not all buildings can be completed in one week when putting the same number of peasants on it, for example. I built half of the buildings in one week) for everything except farms and huts.
- Make the AI attack the player once in a while.
- Not sure if it's possible, but improve the pathfinding AI on walls. Sie
ges (you have that typoed) take ages because you have to run down every single dude on the wall by yourself.
