Elder Scrolls has always been notable for its deep NPC interaction. The whole AI is structured to make characters seem more alive and interesting. In Skyrim I felt this was accomplished beautifully, but I think they really missed some opportunities. When an NPC surrendered, he didn't actually surrender, he just knelt for a moment and started fighting again. When an NPC ran away, sometimes he'd get help but if alone he'd just turn back around and attack you again at low health.
I think those simple, small details would make for a much deeper experience in an Elder Scrolls game. Enemies that can actually surrender and run away, and many that will just try to scare you off (as many actually did in Skyrim). Bandit gives up? Tell him to turn himself in, or take him into town yourself for a greater reward than you'd have found on his body.
But how deep can we expect TES:O to be in this department, and what standard should we hold it to? Is it justified to demand a deep AI system for an MMO, or will we just have to accept shallow proximity-aggro mobs? (I suppose I don't have a lot of experience with newer MMOs, so I don't know what's out there for comparison.)
And of course, how much do you think this will influence your enjoyment of the game?
Would like to hear your thoughts.
