A certain masochistic streak runs through the gaming community, one which judges the quality of a game purely on how hard it is.
Which is not to say that challenge cannot be fun. I’m a huge fan of Etrian Odyssey IV, a game which attempts to brutally shut down the player at every turn. But what makes the game fun is not just that it’s hard, but that overcoming this challenge is a fun experience. The battles are fun, the dungeon exploration is fun, and you get a strong sense of fulfillment from overcoming the challenges in it.
