Thanks for answering that one for me StingingVelvet.
So yeah, Jerykk, what I meant with that illusion of freedom is that Crysis 2 had huge areas with places you absolutely didn't ever bother to go to because it didn't make sense AND in many cases I think you even couldn't go everywhere even though it gave you the impression that you could. What you got was ridiculously and unnecessarily big areas which were one of the reasons Crysis ran like crap on a futuristic PC.
In Crysis 2 it's undeed more confined. But what you get in return is very -- very! -- solid gameplay and much more detailed areas.
I'm sorry I thought you implied C2 sucks. But honestly, if you haven't tried C2 yet.. there's one pearl of a game still waiting for you to be played!
