How about trying to read the gameplay Crysis tries to deliver before making your assumptions
Crytek employees have been interviewed countless times and explained in detail just what can we expect from the game.
I've been keeping up with the game since it got announced and from what I've read and seen so far, the games you mentioned dont even come close to what Crysis will deliver
And the games you mentioned arent even in the same category as Crysis (gears is 3rd person, r6 is tactical and cod is historical fps)
Its really annoying to read that most people think Crysis is just an eyecandy game and nothing more. If you really know Crysis, you'd know graphics is only one of their priorities and that having a good gameplay experience is just as important.
