Nachimir, noted Unreal Engine level designer, has written an article titled 'Videogame Aesthetics' that explores the push in videogames towards photo-realism. Here's a taste:
So how is our progress toward photo-realism? We obviously aren't there yet and won't be for some time to come. Take anything that's currently at the leading edge of the photo-real push, such as Project Offset or Unreal Engine 3. You'll certainly find some very pretty and visually impressive stuff, but it's still not quite good enough to dupe. Despite claims of cinematic quality, you can still see polygonal outlines on models, if you look. Photo-realism will have been achieved when, as a photographer and level designer, I can swap those two parts of my portfolio and actually fool people.
