I think it would be pretty cool if we were able to slowly build up rapport (or at least have them gain knowledge of who we are) with some NPCs dependant on how often we did leves/quests for them. Sort of like fame in FFXI, but a bit more NPC-specific. I only say this after Claroise calls me a stripling for the 100th time. ;) I'm not bothered by that, but I thought "Wouldn't she know me by now? Why is she surprised?"
