Let's just say MS decides to really ditch used games in favor of buying new games to be registered on just one console... But here's the catch, MS may allow used (2nd hand) games to played on another Xbox for a fixed fee. & being a used game, an online pass may already be redeemed, which means buying the code to play online isn't included yet which will be a separate purchase.
So which brings me to ask, are you willing to pay a set amount to gain access to used games? If yes, how much are you willing to pay? If not, will this be a major turn off for gamers & will this practice doom them to failure next gen?
Anything that requires a code or download of any kind is a no go....these restrictions will keep you from owning this content as we move from generation to generation of consoles. Any attempt to restrict, lock content to one console, require online connections....etc...and I will find somewhere else to spend my money.
