This is pretty interesting... 

....Slashdot points us to the news that Atari has started suing various websites that posted reviews of new games prior to the release date of the games. The reviews are negative, but the real problem, according to Atari, is that there was a press embargo on reviewing the games, and if someone has a copy of the game prior to the embargo and hasn't agreed to the embargo, then it's clear that they pirated the game.

...Suing those who review your games (even if the reviews are not good or if the reviews come out early) is a sure way to make sure many sites refuse to review anything you do again.
