Certainly not. Software-wise it's a monster. The fastest selling next gen game so far and it beat holiday launch juggernauts such as CoD Ghosts on PS4 and X1, NSMBU and the bundled Nintendoland.
As a system seller it appeared to do not as good during launch but hell the game was known from the beginning and that was a huge reason why the Xbox One sold as much as it did during launch.
Without it I wouldn't be surprised if Xbox One numbers were 1 million lower by this time.
