Crysis 2
Crysis was most likely the most fun single player experience I ever had on pc. And no, it wasn't just because of the jaw dropping graphics..some of the most fun AI I've ever played against was playing this game.The ability to play missions and attack them from any angle with the nan suit was incredible. No consol single player experience can even come close...
Of course, the problem with Crysis is regardless of your rigs power, sometimes the game just flat out won't work with your set-up. This happens far too often thus keeping it from greatness. A shame.
Now Crysis 2 will now be a port to pc(no matter what they say, I won't believe them) due to being released on consol--thus being dumbed down substantially. Then again, I've been wrong before, I could be wrong again. Maybe they will have a very good separate team working on the pc version, or maybe they will find ways for the consol version to capture the magic of the first one. It will be interesting to see how this turns out.
