GUISE!!1! Want to stick it to Microsoft? Sure you do! In six easy steps, (that Microsoft left in... lololololol those idiots) you can get all you Xbox 360 games to work on Xbox One. Then you can sell your Xbox 360 and go buy some Wii U games because THIS EVEN UNLOCKS THE ABILITY TO PLAY WII U GAMES ON THE XBOX ONE. Your mind is now blown! You don't have to buy that underpowered Nintendo crap and you can play Mario on the system with the best graphics available!!!!!!!!!!!!!!
This also allows you to play Knack on your Xbone, and when you beat the game it also unlocks the ability to play PS4 games.
What an amazing option Microsoft forgot to turn on for launch!
