To be fair, while the detail and well, nearly everything are obviously technically "superior" in the new shots, I believe there is more to say.
The hardware limitations of earlier generations forced the artists to use lighting/colors/textures etc. that while technically very primitive, presented a very strong atmosphere and distinct identity that played a large role in creating the "feel" of the game. These elements helped provide an element of how you remembered the game, its identity in your memory, and even that something that sort of "calls to you" when you are away from the game. In this regard, I feel like it served as a sort of soul for so many games. I would very much like for the modern technical capacity to come WITH the artists still putting just as much into the game to give it, again, a definite identity. In some cases, the older styles (due to imagination filling in the gaps) paired with the artists' going all out - resulted in an overall more engaging experience. For the record, I absolutely am a self declared graphics WHORE. I want the BEST graphics, but more and more I ALOS want the artists that go ALL OUT. Unfortunately, it seems that with the fantastic technical capability we have, sometimes, maybe, the developers have missed this line of thinking and due to the technically impressive offerings they are providing, do not feel as much need to develop/push the artistic elements (the soul if you will) as they did when the tech alone couldn't carry much weight.

Wow, better than i gave it credit to be fair
