You must login or register to view this content., today LazyGamer.net (linked above) reports that Sony has confirmed DC Universe Online PS3 discs are locked to a single PSN account connected to their first player.
Essentially what this means is when you buy and play DC Universe Online, your PSN account will be automatically tied with that specific PlayStation 3 game disc.
If other PSN accounts try to play the game using that disc, they will be denied. Only you, the first player, will be able to play it.
To quote: "We discovered that DC Universe becomes linked to your account when you activate it, destroying your ability to sell it, trade it or rent it.
The folks at SOE were very quick to respond to our enquiry, and they had the following to say:
“
Once the PSN key has been consumed with a disk it cannot be resold/replayed with the second user adding a sub – only the original consumer can use that acct.”
We weren’t too sure if that meant that a new code could be obtained by a second hand buyer, or if the disc and account were seen as one, so we wrote back and got the simple and straightforward answer that: “

isk and account are one”
So there you have it, confirmed from SOE themselves. Once you have bought DC Universe Online, it will not be usable by anyone other than the original user of the activation key.
So once again, be warned: If you see the game for sale second hand without its original activation key (highly unlikely) or want to sell it off, it doesn’t work that way."
This is so stupid! Now lets say you have a little brother who wants to play, he will have to play on YOUR account. Because the disk won't work for another! Soon everything will be like the comic below.
As Garf says "Just dont buy the game. Sony will soon change there minds about this."
