Believe it or not...
Crysis is actually my favorite stealth game. In it's nature, you're given the option to take two approaches to most objectives: Rambo or Bond.
I find sneaking around to be a much better strategy. Even when you have the ability to temporarily cloaked, the ability to decipher and perform orchestrated kills to avoid detection is no easy task. Really, people anti-hype the game because their computer can't run it, but Crysis doesn't need to be run at very high for it to be a great play.
