The greed Island arc from Hunter x Hunter shares a lot of similarities with Quality assurance in another world, it's based on the premise of a game world with intuitive use of game design (even though greed island is a game based on nen and runs in real life). Both manga have an aspect of tabletop RPG with the allure of following resourceful characters understanding and exploiting a specific set of rules.
