Mine would be arbitrarily slowing down a character to maintain horror in a game. I get if there are reasons like age, injury, or location that could provide context, but don't turn my legs into molasses because you need to time the jump scare just right.
My Skyrim and Final Fantasy games had so many useless potions and poisons by the end.
Dragon Age Inquisition had its flaws, but at least they made acquiring and using items less stressful.
