This will be my first Uncharted, but to be honest I'm not expecting much. Sure, I haven't played the previous titles (yet) but from a spectators view it just doesn't seem more than "good", or at least not as good and perfect as others say, in my opinion.
However, I praise ND for TLoU (which I have played), that game truly is a masterpiece. I hope I'll enjoy U4 just as much, bring it on!
