The only really pretty moments in MGS4 and Uncharted 2 are FMV whilst KZ2 uses a lot of misdirection to hide the flaws. All very much possible to recreate on the 360 for the first two just use two discs and play an appropriate FMV in response and for the latter just make a really really dark game.

 Most of Uncharted 2, graphic and technically wise, is amazing comparing to any console games out there. How can a gamer say that the only pretty moment are in FMV???

Because I've read a few of those stupid comparison threads and the only images posted are from the Uncharted 2 cutscenes. I've also got Uncharted 2 and I've noticed that the significantly good looking parts are the cut scenes.

Sure, if you compare the U2 cutscenes to regular gameplay from other consoles then yes it does look very unachieveable, perhaps moreso on the Xbox 360. However when you compare gameplay it looks a lot more plausable. It still looks great in gameplay, but the real gameplay shots are actually within a plausable striking distance for other developers working on both the Xbox 360 and PS3.

Do you realize the cutscenes are done using the ingame engine? Gameplay and cutscene looks quite identical to me.

Do you realise that the bullshots created for public consumption which were supersampled from 15-30megapixel resolutions down to 1 megapixel with some extra shader effects are done using the in game engine?

haha, if you said to me that the pictures of the burgers at the fast food joints were truly representative of the food you get at the drive through window you'd pretty much get the same answer that everyone knows that they are bullshots and the same applies to games. The pictures I see on the forums vs the pictures I see on my 53" Bravia are completely different.
