Make no mistake about it.
Crysis is absolutely gorgeous. The game's a great achievement for Crytek in pushing the PC as even the best systems today have trouble handling the game in all it's glory at high resolutions. While there are a small variety of enemies for a sci-fi themed game, the AI does do some pretty cool stuff. The water effects are, in my opinion, better than
BioShock's and that's saying something. I just experienced my first crash after 5 hours of playing though so let's hope that's a rare occurrence. You have to love a game for being able to throw chickens at your enemies.
