Well, I have to admit that some people just never use this skill called 'reading'. Maybe some of them don't even notice that there's more than one page of comments on this thread. It's almost... it's almost like living in a house full of Bloo's. (Scary thought, I know.) One way to combat this would be if the top post was edited to let people know this displeasure (with appropriate flags, of course.)
To the bloke from overseas who doesn't feel it fair that non-US citizens (such as myself) cannot recieve the secret codes because they're only advertised on US TV: have you read the "For Parents" section of the game? It mentions the game is only open for US citizens. Thus, by registering, you and I lied about living in one of the 50 states! (*gasp* Horrors!) So, as far as they know (legally), they are being as fair as they can be.
...even if they're discriminating by nationality.
