After completing the game we felt compelled to return to old haunts and, if you'll forgive the phrase, pwn them. Really put in a bit of showboating. On a first play of Crysis you feel that the odds are entirely stacked against you, but the deeper you go, you become increasingly aware that despite the challenge, you do have the facility to start toying with enemies like a cat constantly releasing and then recapturing a half-dead rodent.
Obviously, at some point you will always bring the high explosives out to play, but the early Korean sections of Crysis make it possibly the most replayable shooter we've ever played.
Still, there are issues. Enemy AI is either very good or absolutely pig stupid - and very little lies in between. Grunts manning vehicle machine guns are lost as to what to do when you're close by, while those on gun emplacements are often oblivious to World War III breaking out a couple of metres behind them. Every now and then you come across a soldier who just clearly doesn't know what he's supposed to be doing.
Something that really surprised us though was that the vehicles just aren't as much fun to use as they were in Far Cry. This is presumably because Crysis' vehicles have been designed with its 'Counter Strike meets Battlefield' Power Struggle mode in mind, and the added realism and more cumbersome handling that this brings just lessens the feelings of freedom and fun.
