lolwut? they were more stupid than the NPCs in skyrim, + most of them where standing still on their place during ALL THE GAME, you maybe wanna play it again...
and no, you can't
and no, you can't
You're trying to change the topic to activities of NPC's intead of their dialogue because the only thing you could come up with is "they were more stupid"?
In Oblivion NPC's greeted you with "hello" and "good day". Not with "Do you come to the cloud district often? Oh what am I saying, ofcourse you don't" every single time. I prefer Oblivion in this matter.
