I find when publishers talk about used games its pretty disingenuous. The fact is that the number one problem for them in the used games market isn't ebay, or Amazon, its Gamestop. And yet every time the preorders roll around they always hand Gamestop the best preorder bonuses. Then the day comes around for me to pick up my game and the reminder on the phone is telling me about an extra 25% or 50% or whatever is I trade in some games at the same time. So which is it, are used games the enemy and should be combated at every turn or are those same retailers your bread and butter?
Nicole brought up the best point for me in the whole thing, I lend my games out to my friends and vice versa. Having a game tied to my machine will be a big problem. But it all comes down to this, either both the new consoles will have this tech or neither of them will, because who is buying the machine that restricts your games?
