If you dont plan to play in at least 45-60 minute sessions, dont get this game. You can only save at designated save points. So you are forced to play for long periods of time until you reach a save point, or you find yourself replaying portions of the game. You cant pick it up and put it down at will. And the controls and screen are to cramped for the expansive environments. It really just doesnt work on mobile.
