Crysis is a great looking game, but I want to interprete great graphics as what we see on screen, rather than how much power a game can draw from a typical GTX 295.
In my opinion, KZ2 and UNCHARTED are more impressive than what I witnessed in Crysis. With Crysis, there was the initial WOW. I mean the first time I saw it running on my PC, (opening plane scene, halo jump etc..down to the beach side..to the forest...IMPRESSIVE), but that was what Crysis looked like for the most part. When I got to the snow section that looked amazing too, maybe even moreso than the prior part, but that was basically it in terms of WOW moments.
One thing can't be denied though, as amazing a looker as Crysis is, vegetation in the game is pretty much the same throughout, also; the detail on vehicles, explosions and destructability, lighting and effects are not as impressive as what's shown in KZ2. Trees all break in a cookie cutter fashion in Crysis which can look a bit repetitive and jarring. I've heard some mention on textures, well, the people who are trying to knock KZ2's textures are pushing it, because these are some of the best textures in a shooter today, up close they really stand up. Crysis textures are amazing too, but there was this section near a small boating dock that really looked sloppy to me, sand and water looks AMAZING in Crysis, but rocks need some work.
In essence there's always something to nitpick in graphics, but I believe we must be a bit more level headed with our blows everything out of the water comments. In terms of shooters, Crysis does some things better and KZ2 does some things better, nothing blows anything OUT OF THE STRATOSPHERE between those games. IMO, it all boils down to scale against more conservative levels.
Having said all that, UNCHARTED had the most WOW moments ever for me this gen, still have to play MGS4 (though I've had it day 1). Just platinumed UC recently and boy does it hold up, it could be easily argued as the best looking game to date. I remember when I first played it, I was really floored by the fortress level, the lighting at the customs warehouse, the detail in the underground caves when the flashlight lit it up etc etc. Replaying it again recently, I was wowed by the lighting in chapter 21, that's when you come back to the church to face the final onslaught. The lighting typified the wake of morn and it's probably the most impressive I've seen in terms of believability, and yes, the last level impresses time and time again, with the rainfall and the last cutscene is the best I've seen in a game to date.
Point is we can all argue, what uses the most specs out of which or what. I've presented what has impressed me from a visual standpoint, I don't care how it's done, just that it's done. The variety of the environs, the best texture work in the biz and some of the most impressive lit scenes makes UNCHARTED the most impressive game IMO.
