I have mixed feelings about hexcrawl adventures.
On the one hand, a hexcrawl has the potential to be a fun puzzle box adventure with geographical locations serving as evidence for larger schemes or ancient histories waiting for the players to discover.
On the other hand, I have never seen a group of players embrace the exploratory nature of a hexcrawl adventure.
Maybe I handle the adventures wrong when I attempt to GM them, but in the past the best experiences I have gotten out of hexcrawl adventure modules is in using them as a treasure box of resources to throw into a campaign. Maybe this is how most other GMs use them too?
