OK so I finally installed Crysis and did a couple of levels. Hahahahaha!
OK so it looks very pretty, I'll give them that. But apart from that it's Far Cry. The AI doesn't seem to have changed at all. They may have become more stupid, or it may just be that the environment is more difficult for them now. Actually no: Several times I've had AI not even notice me when I'm standing right infront of them. Often they'll continue to shoot and yell taunts at a position where they last "saw" me, even though I'm still in plain sight, just in a different position.
And the crappy scripted storyline sequence triggers still don't work sometimes - just like Far Cry. I've got half-way into the second level and the game has just stopped - no objectives, no idea what I'm supposed to do next. This is with the patch - god knows how bad the original release version was.
The physics are pretty kooky too. At one stage I picked up an empty cardboard box inside a building, and knocked several interior walls down with it while trying to take it outside. I also watched an AI try to man a machine gun, who tripped over something I couldn't see behind the wall of sandbags which not only killed him, but catapulted him out of the fortification and deposited his body in a crumpled heap infront of me.
I can only assume they spent nearly all of their time making it look pretty, because as a game it doesn't actually work. It's very funny to play it just to find out how broken it is, but I don't think that's the sort of entertainment they were aiming for.
