> You play as a feudal ruler

More specifically, that means that you have other rulers under you who may be providing the bulk of your armies... rulers who may have designs on your throne, and their own allies. And even if they're theoretically loyal to you, your son may be at risk of being stabbed by a brother-in-law with designs on your kingdom - leaving your daughter in a very delicate situation only a few steps away from Game Over. Perhaps that will mean it's time to replace your wife and try for a new heir (good luck with the papal divorce politics, better have some poison ready in case that doesn't work).
