Some Notable qoute!!
Killzone 2
"In a genre where technology plays such an important part in defining the gameplay experience, Killzone 2 was a world apart from its competition."
Killzone 3
"Whether it's down to improved art direction, enhanced tech, or (as is most likely the case) a combination of the two, there's no denying that Guerrilla's latest shooter is a clear visual upgrade from Killzone 2.
Probably the biggest difference in the sequel is just how much lighter, brighter and more sharply defined the visuals are in comparison to Killzone 2. The dark and grungy atmosphere we're accustomed to rolls out across several levels, but the combination of a new anti-aliasing technique and dialled back post-processing allows more of the detail in the core art assets to shine this time around. When the location shifts to the more exotic locations in the game, the detail level is phenomenal - after the superb jungle level, the Scrapyard stage in particular stands out as a real visual highlight."
I also read that the only advantage of uncharted is it has veggies on it. 
This thread is phenomenal. Keep it going.
