Note - I have not played the adventure, only read it through
The story line and the idea of it being customisable by the DM is good
My worry is its not very straight forward to run, especially compared to those in other source books or the 1st edition rulebook.
As a "starter" mission in the main rule book a lot of newbies would be encountering it, and i feel it requires a lot of work to keep it organised,
