Extro is free to try and mount a technical conversation if he wants to. There's really nothing to argue about though, he says he doesn't care about the technical achievements, and is in fact blind to them, while hating the art style. Oh Well. I certainly never said the graphics were revolutionary. Evolutionary sure, but you can't trigger a revolution with graphics these days.
I can talk about deferred rendering, or indirect lighting, or polygon counts, of show examples of the physics that are probably some of the best ever seen thus far, or even talk about how the game seamlessly handles environment streaming, or how the enemies have volumetric liquid physics based blood, or how each model in game is so detailed as to have eyelashes, or how the smoke is all volumetric, but all that will result in will be a circular argument where he says "lol it doesn't look good to me, who cares, it's not impressive technically".
Random example, Splinter Cell, aside from the lighting, looks a little 'high quality Xboxish', you want to know why that is? it's because it's spending a ton of resources on that indirect lighting. The same stuff Killzone 2 uses, while using volumetric particles like no tomorrow, with absurd polygon counts, with an incredibly in depth physics system, with DOF that's based on distance (so you don't get that 'flat wall' blur you see in other games) With enemies who's bodies use blended body physics and animation to react when hit (Grunts just turned around in Halo 3, much more primitive). I could bring up examples until the cows came home, but Extro would just say 'lol nothing special'.
Of course we still have to see if Killzone 2 will be a good game or not, but visually, it's pretty top of the line. "low res textures" (which CoD uses to) or not. Although I agree the top of the dropship needs some work, but everything was still a work in progress.
