Great game with great artwork. I am really enjoying it. You take a delve to a location, explore till you reach the boss or end challenge, sell treasure, re-equip or upgrade/train and delve again.

Info on how to create you own delves are provided in the rules and aren't overly complicated. 

Update: The new edition dropped with adjusted rules. They flow really well. Just kinda sad that we lost the pirate delve, but its not hard to recreate it.
