Not much is needed to say in order to describe this game!
my advice, even if you cannot run this game on the higher graphic settings, play this game for the fun's sake. I would still say that Bioshock is the best FPS ever, but this game is something else. The only problem that I see in the game is that it is so easy even in normal difficulty, and some scenes that could have been more realistic are left out. and by the way I think the game should have been longer. 8 or 9 hours of Crysis is never enough! but if you get the huge level design into account, the game's length would easily be forgiven
I don't have anything else to say!
