You're wasting your time. The NPC could come over to your house, clean and cook you dinner and some people would complain that they only want them to be boring cardboard cutouts who stand in the same place day and night.
I have came to that conclusion as well. No matter what, some people dislike TW3 so much that they just cannot bring themselves to give credit to one of its strengths.
As much as I hate DAI, I still recognize the good things it does like customization, great characters (minus the dull IQ and villain) and indepth lore. It is just that there are nore things I dislike about the game than I like.
Some people are just either extreme in their dislike of TW3 or they just are trying to not "give TW3 fans the satisfaction" of admitting to it's stronger points.
But you are right, TW3 NPCs could be the most realistic NPCs ever seen in any game and some people will still have something to say that makes it seems like it aint so.
It doesnt take an expert for someone to see that the city/town enviornments of TW3 are more detailed then that of DAI. But to admit to that is to admit that TW3 does better than DAI in an area and to some, they are just not willing to publically admit to that.
