But.... there ARE missions like that (story as well as side quests).Alright, alright. Should have worded it better. Not like protecting them in the traditional sense.
Escort missions in which I have to pick someone up with my Gravity powers and fly them across town or something. The whole thing is, take something like Assassins Creed 2, which had plenty of stuff to do around the world and, granted, the series eventually went overboad with all of that I still think that GR's world could use some more stuff to it.
