Many, many of the pre-battle speeches. Some of them use Refuge in Audacity and Vulgar Humor then finishing up the speech with a religious statement. It is just so weird to have a noble warrior say he will sex up the enemies women in one speech and say that he is doing Christ's work in another while calling the French smelly and unwashed using old terms like "knave" like they're candy.
English General: Well hail, slap my thighs and call me for dinner! I see a foe worth the killing and lads beside me who are up to the mark. I can also feel and inspiring speech coming on, so listen to me...
Mongol General: [to his enemy] Struggle if you like, I will take your lands and women, regardless; You will have no rights, once you are my prisoner; Was it your brother I killed? You all look alike to me.
The absolutely ridiculous ways spies sneak into places and the strange ways your assassin can fail. How about putting a poisonous snake on the ground of a general's bedroom and having it slither right out of the room or even better, the snake bites the assassin. Or the assassin hiding behind a door and the general opens it so fast, the assassin gets hit in by the door in the nose or, even better, is KILLED by the door while the general runs away screaming. Ever see a spy hide in a bush or haystack and get stabbed by a suspicious guard? Or most ridiculous of all, trying to drop a rock on a calvaryman?
Becoming very trustworthy and getting max happiness with another kingdom by offering ONE florin to them and having them accept a few dozen times (in one turn by using the gift option), then IMMEDIATELY getting attacked by them next turn making it impossible for anyone to ever trust them later. Florin for you thoughts?
