Oh ho, what's this?
By all means, elaborate. What subtle changes are you referring to, exactly?
*scoots chair closer*
I'd love to hear that, too, especially since a gripe I have is that only raiders, enclave, BOS etc ever respawn in my game. I've yet to see Arefu or Megaton or any other place grow after making them safer. Maybe the changes are too subtle for me to notice.
It seems a bit odd that the only "new" people coming into the area, and there are lots of 'em, are all bad guys whose only reason for being is to serve as targets in a shooting gallery.
