In Civ V I enjoyed how the Al leaders would interact with you, by either sending sassy messages to you or by complimenting you. There were many types of screens you would see that are non existent here.
Diplomacy now is much more rigid either accepting or rejecting certain diplomatic moves. While I like more diplomatic things you can do, much of the personality is gone from those interactions. The computers feel more like empty husks that I end up skipping or quickly going through the diplomatic interactions now
