I do agree in some way but then most shops like GAME and HMV which are famous for there 2nd hand deals would go out of business.
I do buy most of my games new but from time to time me and my cussins swap games to get the trophys and play some online while were at it.
So this would be a big problem.
If the code could be used 5 times like gamsharing then that would be better
