So, I just got finished playing the story mode, and I loved it! The graphics, the story, the gameplay, its definitely going to get a replay at some point. I love the scale of it, how you actual feel like your in this huge wrecked city, I love looking up at the skyscraqers and marvelling at how nice it looks and how well it plays. I just wish there had been a final boss to fight, it wasnt the grand finale id hoped for.
Downsides: AI is sometimes really stupid (at one point I shot a load of army guys are one was just standing there drinking whilst I was doing it) and I know up close a lot of the textures dont look as sharp as they did in the original Crysis, but really does it matter? Personally id rather just actually play the game than stand around staring at rocks/walls to see the texture quality. Im able to play the game at almost constant 60fps on extreme settings compared to the originals 30/40 so for me its a sacrifice I can live with.
Overall id say Crysis 2 is an incredible game, certainly better than the original gameplay wise. Cant wait for number 3.
