Xbox One will not make you pay for used games. MS finally seen that it was a terrible idea as they'd lose console sales.
I've owned both a 360 and a ps3 I'm not biased to one or the other, most friends play Xbox though. I'll wait to see more info at E3 before making my decision.
Pretty much every article I can find states there is a pay wall when putting in a game not bound to your system and or account. It's good if they aren't making you pay a fee for used games, do you have a source for this as I can't find one?
