The game only really exists half way through..
Apparently the AI was terrible when the game launched, but having played Crysis 2 after patch 1.03, it seems they have resolved most of the AI Glitches, there were a few instances of dumb AI, but negligible.
The first 5 hours or so of this game is extremely boring, alot of ppl have been put off by this factor, infact many just gave up playing...but if you give it a chance the game takes a complete turn and becomes an intense, thrilling shooter until the very end. Graphics: While the game looks great overall, the PS3 version apparently is the worst of the 3, and it shows, the resolution is low, lot of the great effects are missing, such as volumetric smoke and fire effects (burning debris look like animated Gifs) , FrameRates are very low in many levels, I am sure CryEngine 3 can do so much more, but it seems crytek did not utilize the engine properly, nor did they try and utilize PS3 technology...i also hear the PC edition is not so great either. Multiplayer is Fun for few hours, suffers from LAG problems (they don't use zero ping technology like other games)..i wouldn't really count it as a significant part of the game. The Map design is superb, but limited to 6 players.
