The Xbone wasn't designed for core gamers in the first place. Microsoft thought that they were already in the bag - all of their excessive design choices were meant to entice non-gamers; hence their messaging at the reveal was about anything but the games.
This. Unlike with systems such as the Original Xbox, Xbox 360, & PS4, Xbox One was heavily designed as an entertainment/media hub machine first in mind, & not a gaming machine.
Their 1st commercial for Xbox One wasn't about games, it was about the NFL.
