Ofcourse they don't offer compatibility for 360 games.. You wouldn't want your long standing user base NOT buying EVERY new game! Throw your 360s away, kids! They're a piece of sh!t! Oh those hundreds of 360 games? Yea just dump them on ebay, sell them for 20 cents or lock em up for 400 years in the future where they'll be worth 40 cents!!!
Xbox ONE, when we're not sure what to do anymore, so we just start off at square ONE!
After the 360 previous squares are bulldozed, obviously.
