This is my "go to" adventure anytime I want to start up a new group or game. It's a ritual for me, roll up characters and run them through the halls of the lost Castle of Quasqueton. I still have my copy that I bought all those years ago and it was also one of the first PDFs I purchased from WotC. I never really expanded on Roghan the Fearless or Zelligar the Unknown save that they were long dead and their Castle was now overrun with monsters.
It is one of those adventures I can run with zero prep time and each time I learn something new or remember something I forgot.
This module is simple, easy to use and can adapted to any campaign world and even any game.
It is a perfect module for the Basic game.
