Ahh, I stand corrected.
Fidelity is much better, aesthetics are better in wow. Wow is just more colorful and appealing in a lot of places, instead of more realistic.
Keep in mind, I'm not talking about how the graphics look close up or even in action. When I think of wow looking good, its more about some of the big outdoor areas, like the wide open fields and platues of the Tauren starting area, or the farming villages of one of the earlier human areas, or the snowy mountains of the dwarf area, or even the area around the undead starting area with the really tall trees. Like, the sense of awe that can come from just looking around a place, wow had a lot of that in a lot of places, I don't remember much of that at all for me in GW1.
