MGS4 is a very very beautiful game but lacks some of the technological edge other games have.
Nut the models are amazing (not the animation).
On the other side I once again will support the opinion that the vast majority of gamers who didn't play Gears 2, think (or want to think) that gears 2 is just a graphical upgrade comparing to the first one.
Honestly, screenshots don' t do justice in Gears 2 case.
The lighting, the details, the smokes-dust, the scale. I still play some sequences (ie the Nexus) just to take a look of the beauty.
