Any examples you have of when an npc really made you go wow.

Lastnight I'm in Windhelm up by the enchanter sorting out my items and making new enchanted gear, I dropped a few items so my inventory wasn't as confusing, this guy comes up to me and says he noticed I dropped some belongings and asks if he can have them, I said no. I was very surprised that the AI was that smart.

Another is Faendal. After marrying Camilla I sent her to live in my Breeze Home and suddenly Faendal the archer from the love triangle that loved Camilla starts popping up and going into my house. Also I got a friend of his in Riverwood killed by not killing a dragon quick enough. Anyway he says mean things like I'm not a good person and I'll get what's coming to me. So I moved to Solitude and sure enough he is in my house using my alchemy lab and arcane enchanter. I'm gonna kill the annoying twit.

Also I killed some lady out in the wilderness and now this guy comes up to me from time to time saying thank you she had to go. I don't know who either one is.

I never really took the time to listen to people and now since I see how deep they really are I love listening in on what they say to eachother. They are smarter then I ever gave them credit for.

Only thing i can think of is when i first played on the 11th of November, i jumped onto a rock where an enemy bandit could not hit me, i was about to do what i did a lot of in Oblivion and that is exploit the dumb a.i by jumping onto a rock and shooting him in the face as he stands and watches me. I was pleasantly surprised to see that the a.i will run away and cover behind a wall when ever i do this now. I'm not proud of trying to do it but i did it out of habit more than anything. Glad it has been addressed.
