Then, I thought about how you could steal the goblin totems in Oblivion and put them in other Goblin caves, and how they would duke it out for the totem.
Which got me wondering, "What will happen if I steal something, and then proceed to place it in another's house? If the NPC I stole from found out it was in someone else's house, would he hold a grudge? Could I eventually get NPC's to kill each other?"
I think I'd like to see something like this in Skyrim.
Thoughts?
EDIT: I spelled the title wrong, and it was misleading. Could it be renamed to 'Can we manipulate NPC's?' instead. If a mod sees this, thanks.
