The thing that always bugs me is when your character should be able to get past an obstacle, but can't. Whether that's a tiny "wall" that a human could just step over, a couple of cars blocking a street, a locked wooden door when your character has a grenade launcher, whatever.
Probably the most egregious example I've ever seen is in Jedi: Fallen Order. At multiple points in the game, you're blocked by small metal bars, like a jail cell door. I have a lightsaber! It's made worse by the fact that at other places, you have to use your lightsaber to cut through fairly similar blocked paths (they look more like tubes than bars, but whatever), and also by there being blocked paths that are more plausible, like force fields.
It always bugs me. If you don't want me to go that way, then put something there that would actually prevent my character from going that way.
