You ever choose a difficulty that was way too high or low and it at least partially ruined the game or that run of it? Or maybe you missed some items by picking too low a difficulty by accident or something. Not sure if I've ever done this, was just thinking about it. I did a Halo 3 Legendary playthrough as a teen, which I remember being tedious though I don't think it ruined it for me because I finished the game and liked it. I've probably missed some true endings somewhere since I almost always go normal/medium difficulty in games.
