Critique and Advice; the treadmill of adventuring.

As my fanventure test run on 4chan is slowly approaching its climax, I'm starting to get anxious about running it here "for realsies". Even though the story could use some sanitizing (obviously), I grew very attached to how it played out. I don't know if I want to do it all over again, risk derailing the story and killing off a potential ally. On the other hand I don't want to recreate the story 1:1, obviously certain scenes could be rehashed or expanded upon. Is there a possible compromise?
