Every game where the player character follows another should be required by law to have a Rockstar-style "hold to walk at same speed" button. No forcing the player to walk at a snails pace either, it should be optional.
This so much. I hate that some games don't have it. I hate how Forza doesn't supply one. So annoying when you have to adjust the TV settings back and forth.
