This is bullshit...
So what? Should General Motors sell now cars with an only-for-first-buyers protection code for ignition in order to promote the selling of new cars? Can you imagine no second-hand market for cars? (and of course that used cars sellers do way more money than GM, ha-ha-ha 9_9' )
That's stupid. I can understand if they are pissed off with piracy, but it is stupid to close the second-hand market of legal copies.
First, that make the games more popular among those without money to get a new copy (without that, the only way is piracy). Do you think GTA or Final Fantasy would be that big without it? Second, who spend time to sell an old copy is generally trying to make money for new copies (and, wait, if the second-hand market is so huge is because a huge amount of games was already sold previously).
Greed, man, just too much greed. They don't even have brains anymore to think beyond the immediately money in front of their eyes =P
