Recently, I was a player in a campaign using the Knave rules. The setting was inspired by Norse mythology close to the end times - Ragnarok. Amongst many locations, the Referee had put in set-dressed versions of Keep on the Borderlands and Barrowmaze. Despite the delves and riches, I never actually reached level 3 or higher with any of the characters I played. I delved deep with only 5 hit points, and it was great!  They all have 5 hit points, but so do you.
