I had more fun with crysis 2 and thought it looked overall better. The lighting makes a billion times more difference than any texture resolution could in my opinion. I don't face hug walls so i can scrutinise texture resolution, so bar the funny floating rubbish textures, it looked better. Not to mention, upgraded textures is an easy thing to upgrade.

Physics seem to be mostly ported from the first but scaled back in usage.
A few destructable road items etc /= to numerous huts you can break in crysis 1. Destructible trees still present in Crysis 2, but to a less extent, more unbreakable types + obviously not much jungle.

Generally preferred controls, functionality is pretty much identical, Q and E for default mode switch is far far better than having to scroll wheel press and move to the side. Lets face it, if I was wearing a nano suit, I'd prefer the crysis 2 controls linked to my suit not ..oh crap, went into the wrong mode on my billion dollar suit again lolz, like whoever designed the UI of the suit was <10 years old.

Except for any preference to sandbox delinearising features for gameplay, all this game needed is apparently higher textures and tesselation and 90% of complainers would shut up...
