Another thing you have to keep in mind is that with our eyes we can look around us unlike video games, we have to move our "head" to look around. the video games eyes are always looking straight and wherever the head is aiming is what you see, plus the limitation of peripheral vision, it makes for a very hard game to get close to "realistic"
If we did get "As real as possible", you have to include what you see everyday yet not notice it like your hands and body but also your nose, upper lip (If you look closely, you can actually see your upper lip, try it :D) and other features.
Only way this will work out is through Virtual Reality which even then peripheral vision is still limited
Untill video games become like Tron, we wont be seeing the characters nose in the near future.
