You have to hand it to the ratings board. They usually are the first people to ever see the good parts of a game, because they have to tell you whether or not you are old enough to buy the thing. But sometimes they also are the first people to ever even hear about a game or see that it exists, such is the case with Crysis.
Crysis 1 was released exclusively on the PC a few years ago but now it seems that it may be making the jump to consoles. The ESRB has rated the game as Mature and lists it for both the Xbox 360 and the PlayStation 3 as well as the original PC rating. There was no description of the title at the moment and, being as there has been no confirmation from Crytek themselves, this can only be seen as rumor at the moment, though we have reached out to Crytek for comment.
