One thing I wouldn't mind seeing from NPCs is a little vocalization when you talk to them. Easiest way to explain this I can think of is in monster hunter tri for example, when you go talk to the chief and he's all like "Hmmm" when you initiate dialogue, or Jr. who is a little more upbeat and like "'Hoy!". That kind of thing I wouldn't mind! But voice overs.. I think I can live without D:
