Ah, interesting. I guess I was wrong. Apologies. Can you imagine the blowback if a particular publisher didn't support used game sales?
Even if they all supported it thats hardly "support for used games" as we all currently enjoy with the new (old) policies.
Thats not you being able to play used games. Thats the ability to sell your game licence at certain retailers, if publishers let you. Or you could give it to a friend...who had been on your friends list...for more than 30 days... again if the publishers let you... and he couldn't ever give it back or ever give it to anyone else.
Compare and contrast to doing whatever the hell you want with your game like you get now, not having to give authorised retailers a cut, letting as many people borrow your games as you want, buying and selling from anywhere, the ability to rent games etc. etc.
There is a reason why those policies combined with always-online caused such a massive shitstorm. They fucking sucked.
