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.
Skyrim at least has horses, carriages, and boats for fast travel alternatives. Try playing Oblivion where the only way to fastly travel is fast travel. Morrowind still has the best fast travel system that isn't fast travel though.
I liked that Fallout 4 had the teleporter and the vertibirds if you're playing without fast travel, like in survival mode.
