Id say Lego City Undercover. It's kind of like a Lego-fied GTA, so there is lots to go around and see and do, the characters are hilarious, and its overall a very fun game. Since the story is a bit...less important? to the way the game plays, it can be fun for a bit longer than the others, in my opinion, because once you've seen the story of the others, regardless of how good they are, that's pretty much the whole game.
