So what's the problem? Why is everyone getting so angry about this?
It all spawned from Microsoft's big reveal and alleged rumors about the Xbox One's stance on preowned gaming. A pay wall would be introduced if you wanted to lay a loaned or second-hand game.
Microsoft quickly went on the defensive, stating that the story was pure speculation and that they would be releasing a statement on this matter in time, clarifying what you can and cannot do with the console.
As you can see, the console differs greatly from its predecessor, making Kinect and 24-hour internet authentication mandatory. This left gamers justified in their anger. Microsoft's answer to this? "Buy a 360".
