Quote: sonicbrawler182List of controversial alleged restrictions of the Xbox One:
-Mandatory Installation.
-Must register games online before you can use them. Once registered, you can go offline (think old PC games).
-No backwards compatibility with Xbox 360 games.
I'm not really too fussed on this one, the PS3 had the same issue to until everyone realised that it didn't matter. As an alternate third option, you could have the pre-owned thing; about paying full price for pre-owned games.
I'm personally not bothered by it myself, but I can understand people's disdain towards the fact. I'm sure a lot of people would of liked to sell their Xbox 360's to get the Xbox One (especially since there will likely be trade-in deals at many retailers). Then they could play their collection of Xbox 360 games on the Xbox One, while saving a bit of money on the new console. That plan is ruined though if there is no backwards compatability.
Admittedly though, I am just not that impressed with the Xbox One, and I myself won't buy it (my brother probably will though, as he is a bit of an Xbox fanboy). So whether or not it has backwards compatability is irrelevant to me.
Though I was a little bothered when I heard the PS4 might lack full backwards compatibility, as it means I would be better off not selling my PS3 when I decide to get the PS4. It won't change whether or not I actually buy it, it'll just delay my purchase of it.
