Of course I am not going to copy it all here, but it comes down to the fact that they want to implement chips on cd,s so that if you put it in your PS3 (or 4 in the future) it recognizes it. Then if you put it in another PS3(or 4) it will not work.
Now I don't think they will do this yet, and they have not done it yet.
But it would be a real bitchslap against consumers because reselling games and/or lending a friend a game would be dead.
Well to be fair they have already implemented something similar in that most of the time you are required to purchase an online pass for used games. It all boils down to what makes the company the most money, hell if they could they'd give games away for free to turn around and charge you twice the price of the game for the actual content. Sadly, IMO, it will only get worse as the years go by and gaming companies get greedier.
Luckily I don't own a PS3 anymore. I sold it after the entire PSN network was down for 2 weeks. That was such a humongous fail.
current rumors is that the ps4 wont be backwards compatible either if thats the case ill buy a ps3 for the kingdom hearts remakes coming out this year then wont touch the ps4 unless a kingdom hearts game comes out for it
As long as you don't require an online connection to play as the article suggests then hackers will definitely find a way around this, at least for offline play. They are merely delaying the inevitable.
However for online play, it's pretty clear that second hand disks won't be happening.
