Those screens are nice, not jaw dropping but still nice. Imho, the next gameplay footage will really make the difference, like mgs4 which is nice in screenshot but nothing compared to the trailer they gave us. The animation in GRAW plays a lot.
I also like the fact that you can play in many weather condition, and the game looks really different when you're playing in daylight, dawn, sunset or night...
Personally I would love for MS to embargo any media that doesn't make you go wow... We still have no idea how PS3 games really look... but we are bombarded with in progress of shots of games for the 360... bah!
The fountain and the arches could use a lot more polys. And that's not me being contrarian, it's really the first thing I noticed. I mean they're right there in front, it can't even be LOD.
These look like fake screenshots, 2 of them look like they have had various asset cut up in photoshop and pasted on the screen. There is a mismatch of lighting and textures. It also looks like someone didnt fully mask around the soldiers helmet leaving some weird artifacts.
