Title: The Keep on the Borderlands
Author: Gary Gygax
Rule Set: D&D
Year: 1979 and 1999
Number of characters:
This is one of my favorites, the star rating says it all. The Keep hovers on the edge of sandbox wilderness, one that is your to explore. The Keep is the perfect place to kick off an adventure, the players can obtain all they need to fully explore the environs.
As a carryover from B1, the advice sections are present and highly valuable. There are also handy details such as gossip and the willingness of the lord of the Keep to provide the player characters with man-at-arms and magical items.
Where this module shines is in the tactics provided for each group the characters encounter. Some of them are embryonic or silly, but in keeping with the intelligence level (or madness) of the inhabitants of the Caves of the Unknown.
One of the better things about this adventure is the player mapping is logically constrained, allowing them to make mistakes, but not so bad as to create a mapping nightmare like In Search of the Unknown.
