All provinces--both yours and the other factions'--also now start with quite a few more buildings than before, and everyone can start training better units right away. (Everyone's starting armies are now a bit bigger and better as well; no more starting with just your king and 100 spearmen in your home province!) As a result of all these changes, the other factions' armies tend to be smaller than before, but of significantly higher quality. Since downloading the XL mod, the AI rarely fields massive "fodder" armies consisting of mostly spearmen/archers/UM
That's really what I was looking for...thanks alot Martok !
