Sony has reportedly patented technology that will prevent the use of second hand games on consoles.
According to NeoGAF member gofreak, the patent application was filed on 9 December 2012 by Sony Computer Entertainment Japan, and will work by linking individual game discs to a user's account without requiring a network connection meaning any future attempt to use this disc on another user's console won't work.
Cold blooded. If MS doesn't do this, then Sony will definitely die out as very few will want a console that doesn't allow them to share their games. Luckily i'm not a big gamer or else i'd be annoyed at this. Sony will get some bad press as this would lead to Gamefly/Gamestop making huge layoffs.
