You can say it however you like. As I said, considering how far down the list it is between critical reception and sales and that what is good or not is subjective, to say it as if the game is factually one of the best is silly.
As far as Quantum Break goes, it has potential but calling it the first true next-gen game is giving too much credit to a game we still don't know much about and there are games coming out before it that will likely beat it to the punch for that title.
