The Rotating Labyrinth has very quickly become a staple one-shot for me. Although it can be incorporated into a fully fledged world, being able to just drop the players at the entrance to the cave with a little motivation and let them run is really fun for everyone. My players loved it and were shocked, and I know others will want to play it again and with others who have no idea what is about to happen. The look of surprise is priceless, when they back track and expect a familiar place but are greeted with new sights. This adventure module/map is well worth it.
