One of the first adventures ever printed for D&D and did not age well. Not much of a story and basically just an empty map to stock with creatures. Unless you want some deep nostagia or just want to complete a collection, skip it.
These maps are amazing. A must get if you want to run this classic adventure. Creator really read the material and tried to bring it to life in a beautiful way. They look marvelous and really add to the feel of the game. Hats off.
