I hate to say it, but I think a lot of people get angry when Crysis won't run on their machines, and take it out on the gameplay itself. I found it to be a wonderfully open-ended game. I would replay many of the major fights two or three times, using different techniques. The game let you play using brute-force or stealth. It let you pick guys off from afar with a sniper scope, and blast guys up close with a shotgun. You could steal a boat or truck, or decide to "hoof" it and sneak along in the forest. Even in the level where you got to drive a tank, you could opt to get out and use rocket launchers instead.

I actually preferred it to more "consolized" games like COD4, where respawning guys meant you couldn't play as a sniper, unless the game forced you to do so during the mandatory sniper levels. Lack of quicksave meant you had to replay certain parts over and over if you died. Obstacles blocked your path so you couldn't flank around and attack from behind, while Crysis allowed you to tackle a base of baddies in a bunch of different ways. Crysis allowed you to destroy a satellite tower any way you like. You could drive a car into it, shoot it again and again with a gun, throw an explosive barrel into it, etc. COD4 had you destroy things by using a giant flashing beacon that you had to run up to and press the "use" key.

I found the "openness" of Crysis refreshing. Sure, it had it's faults. The AI wasn't great, and I really didn't enjoy the alien levels nearly as much. However, overall, I think it was a very good game. I wish all games had destructible environments and allowed the player to tackle it any way they wished. I'm tired of being told exactly how I need to play each mission.
