Review embargoes are a very normal part of games journalism. Companies will put restrictions on when publications are allowed to talk about games before they’re released. For previews this is done to control the dissemination of information. For reviews it’s to allow certain publications to have an exclusive, or more muckily, because they don’t want negative reviews to appear too much in advance of the game’s release. It’s potentially murky territory, but since it’s their game, they get to choose the conditions in which they make them available to magazines and websites before commercial release. It’s not unusual for everyone to be told, “Reviews of game X may be published at 5pm on the 26th”, and then you’ll see all the sites have their reviews appear at once.
What’s far more rare is a company attempting to control the publications of reviews after a game has been released. Especially not ten days after. This is what Realtime Worlds are astonishingly trying to enforce for APB.
