Clicking on random NPCs as they walk around is an absolute obsession of mine now, it's how I spend my time when waiting for teamates to sell/train/whatever. The Devs really outdid themselves in CoV!
In Cap au Diable:
NPC: Dr Aeon is the coolest! Giant pumpkins rock!
Totally different NPC: I hate Dr Aeon! Who needs giant pumkins?
I've heard a few Goldbrickers make different references to chocolate now...I have a friend who is convinced that King Midas pays them only in candy bars.
