True. I expect once SV hits the first 100k players having multiple servers on each continent will just make sense anyway. I mean who could deal with 10k people all walking around one Tindrem. ?
If you wanted NPCs to be a bit more lively you could have them give Eavesdropper type clues on occasion. Could be some logic to who says what or maybe its just random. The town crier might hit at an upcoming event, things of that nature.
