A question for Codewalker: Might it be possible to tweak Icon so as to be able to save player-spawned NPCs from one session to another, as a way for each of us to re-populate our own copies of the game zones?
Even if that were possible, I don't imagine that we could assign some kind of scripts for them to follow - travel routes, emotes, etc.
I'm probably dreaming beyond the program's capability, but it's a pleasant dream.
