Which game do you get longer playtime out of? Not sure about this... I got 16 hours on my first playthrough of The Last of Us, so probably that (tlou has new game+ too)
Which game has better multiplayer? Easily TLoU, wasn't a massive fan of U2 MP although U3's was very good
Which game has better graphics? TLoU.
Which game has better story? Hard to decide... going to have to be a tie here.
Which game has better characters? TLoU just because of Ellie.
