I am ganna pick the crysis2 soonish..<.<
for now, for some reason the email was sent to me by GameSpot that the key they gave me can be active on 3 computers. 
The game is sick though…Only downfall that I found is, If you are in the open space and your cloak gets disabled, If there is one korean on patroll and sees you…He sounds the alarm and than there are 10-20 koreans after you until you walk back in to bushes and cloak…
You rarely get the headshot with PSG. Or maybe they had extended head collision detection in CS.
