Other than GTA and Racing games I have to say this is smart and I think cooler than just slapping a number on there. I mean when someone sees "Infamous 3" the first thing they'll think is "well I didn't play the first 2 so I probably shouldn't get that one..." Meanwhile if they see "Infamous: Second Son" it has more of a unique feel with less ties maybe. They can jump right into that one and it mostly lives up to that expectation.
