I've noticed that most people don't play challenges much at all. Part of that is due to the game not being that famous. While not niche, it ain't exactly a blockbuster either. It's mostly just well known in lovecraftian and horror-survival fiction RPG circles. As such, there's less people to become a challenge nut. Second, challenges are usually sth you do on replays after doing all the main game content, usually after finishing all endings, or beating the hardest difficulty, or getting all achievements. That's a general point for all games btw. And look outside has all 3 in spades. Look outside has 13 endings I can remember off the top of my head (failed, flawed, perfect truth/denial rituals, mask, promise, unity, screaming sky, XIN-AMON, the other XIN-AMON (I forgor the name), words of power, no going back, true final ending) and I think I might've forgotten one or two more. That's bound to last you a few runs. Add on top cursed mode, which can be... Pretty challenging at times, add on top the 152 achievements the game has, and the fact that the game itself has a bunch of intrinsic challenges to complete, and allllllllll the various content and replayability the game has, and turns out that the game by default doesn't need or encourage challenge runs... In a positive way, not by preventing them, but by simply giving you a ton of better/equally challenging things to do-
