Like all retards, the guy fails to appreciate that art design is what makes graphics good and memorable. Objectively, sure Thief 4 looks 'good' if you just look at an overall scene, and of course it looks 'better' than a town scene in T2 or T1. But that's no praise, as every bloody game looks good now, even the COD games look 'good'. They look fine but are totally forgettable with nothing that stands out. Once I've played a modern game, I struggle to remember any location in it.
But mention 'Down in the Bone Hoard' and not only the hairs on my neck stand up remembering the audio, but I also remember all the creepy crypt decorations, even the hollow eyed angel monuments, never mind the most loathsome zombies ever.
