I have ran this adventure when it first came out and it is a very well designed adventure. It is easy to run for those not familar with the Dune Universe or for those who have read the book. The adventure is written that you would be apart of house atredies and takes place as the atredies take control of Arrakis. The adventure could be played in a single session and helps if you have played the 2d20 system before. I gave it a 4 and not a 5 star because I felt the errata changes were not needed and added nothing to the game that people could not have done on their own.
