Overstated
Crysis can be very pretty but I could not be one of the lucky ones. Its destructable environment brought my computer to a crawl, forcing me to reduce all texture quality to low to have decent framerates. My computer does not have a 8800 GTX but I am not someone who groans about Crysis with a 7300 GT either. I have a X1950 XT but this game is just... how do you say? I believe this isn't good. Realistic physics is desirable, at least before it polls a heavy toll on performance like this. Call of Duty 4, though lacking those detailed destructable environment, has great compatibility with PCs. Everyone can enjoy the game with high quailty visuals.
Lackluster aliens
I would rather Crysis focuses on the conflict between North Korean soldiers and the US forces. The introduction of the alien fraction is very bizarre which does not match the main theme of realistic combat. I can certainly bring down human foes the whole game! The aliens robots are never accounted for their origin, how they plan and what they are up to. You only know they ain't friendly. All of a sudden, you no longer fight intelligent Korean soldiers but some squids who will just rush to kill you. In other words, you fight clever men and then stupid aliens.
Clumsy bosses
The Korean general has the nino-suit so you may want to shoot him frequently. Otherwise, he may heal up. However, this guy never pursues you but stands at a fixed location. He is EASY to bring down.
The spider monster, namely Exosuit, really pisses me off when it killed many marines but it was not a fantastic enemy either. All you need to do is to stand next to a box containing missile launchers and fire as many missiles as you can and dodge his freezing beam. If he grabs you, keep firing on him so you won't fall from even greater height. The last boss is a mothership thing (we don't even know if it is an organism or it is piloted). Just stay behind cover and it cannot hit you. It isn't worthy but the game guidelines are too simple so I happened to watch how others beat him on the web.
The ending: It ends?
I didn't notice that I had been playing the final chapter untl I seeked help on the web because no tips were given how to defeat the spider and many years of gaming tells me walking in with gun blasting doesn't work against bosses (surprisingly it is the case in Crysis). You retreated to a fighter carrier that reminds me of Quake 4. But Quake 4 has us go back into a long portion of the game unlike Crysis. A sequel is inevitable for such an ending which is no better than that of Rainbow Six Vegas. I have a feeling as if it is an unfinished game when it officially ends.
The good
Even so, I am pleased with the guns. The Koreans are smart enemies that can delight when killed. Shooting down helicopters is amazing so I will surely replay it. If I make an upgrade, the experience may be improved a lot. But it would be nicer that a Xbox 360 version is released so I can keep this PC longer.
P.S. The suit voice
I strongly recommend using the female voice for your suit. 90 % of the game includes men so it is good to hear women's tone with your suit. Also, the male voice is deep and mechanic, bringing me a dim feeling.
