How am I supposed to earn them if I don’t even know what they expect me to do for them? Why do these exist? I haven’t even encountered a game (not even a Fromsoft game, and those guys are notorious for being vague and not forthcoming with info even for guide books) where the hidden achievements were not already listed by a 3rd party somewhere outside of the game day 1, so why not just show them in the damn game?
Well, the fact that you CAN pull up the info at any time is part of the reason why developers can do it with complete confidence that it won’t negatively impact the experience. I personally appreciate unlocking a hidden achievement I had no idea about for doing something unusual in a game but then again I don’t generally achievement hunt in games unless I find them cool to 100%.
