Oh and I dont agree with your graphics point. It does look better, but its nowhere near "top quality modern graphics". Look close, most of the environment is low poly too. Actually not much more polies than WoW. The chars and NPCs look nice, since they have a much higher poly count, but look at the buildings, trees, rocks, even the vegetation textures, etc. And that also explains why its running pretty good on my 4 year old mid range graphics card.
And that explains why you think it doesn't look as good as it does.
