Get it dude. It's absolutely wonderful and in my top 5 ever. They fixed the filters issue the first one had so they are easier to find etc. The gameplay was what received the most tweaks, but I promise you the graphics and the artwork will absolutely blow your frikkin mind. And it's very well balanced out too, between hard core and exploring. I don't know if it was intentional but they really did get it absolutely spot on.
There was one bit that frustrated me a little, but it wasn't being helped by the fact that SLi support was late. I seem to recall a swamp, falling into it, swearing and the FPS tanking which made that part extra difficult. But it was worth pushing on.
