I am finding it very amusing all the frothing at the mouth over the Xbox One. And not just on here, but all over the net. It seems to me that people think they have a god given right to the Xbox One. Microsoft, as the PRIVATE company, selling a product are free to dictate how their products are to be used.
Fact is, no one truely 'owns' their games, you only have a license to use it. You own the physical medium it is present on (the game disc or your hard drive), but the software remains the sole property of the publisher. People have been clicking away rights in this regard for years and years now. Every time you just skip that massive wall of text with the "OMG JUST LET ME AT THE GAME' attitude, you are forfeiting your rights.
As short sighted as Microsoft seem, it is their right to implement this. I can't say with certainty, but I would be willing to put a few bob on Sony following suit, just with less fan-fare.
Buy the console that makes you happy. That is all you have to do!
