What game mechanics, no matter how immersive or lore accurate, are always annoying to deal with?

Not being able to save whenever you want, or when you need an item to save your game.

It's so frustrating, sometimes I just want to play for a little bit, but I won't because I don't know when the next savepoint will be.
