There's just a whole bunch of them in this game, huh?
Do you talk to everyone? do you only talk to the ones with actual names? do you not talk to anyone at all, or do you follow strategy guides to know exactly which ones to talk to?
When I reach a new town I'm usually too eager to bother to talk to everyone, especially because almost everyone seems to not say anything important at all. I do have some periods where I go around talking to everyone though, to see if I've missed out on anything.
