I want to come back. I mean it too! But I can't until they update the graphics engine. It hurts my eyes.
Seriously, the game looks beautiful.
FFXI is a classic case of good aesthetic design overcoming low-quality graphics. The engine certainly isn't cutting-edge (it doesn't even use DX9(!), last I checked), but the whatever else you can say about the game, the art direction is consistent and deliberate. This is a running thread through Square's games. WoW, on the other hand, keeps on top of the graphics game, but it still looks like crap from an artistic perspective. Blizzard obviously put more thought into SC2, which is quite nice looking.
Other games that exemplify aesthetics > graphics:
The Wind Waker / Skyward Sword
Persona 3 / 4
All of the above were released on graphically sub-par platforms (Yes, the PS2 was atrocious graphically, even for its time. It made up for it with the strength of its massive library), but have a striking look you can easily remember envision years after playing them. Compare that to the latest CoDs/Battlefields (with the exclusion of Bad Company), where everything is same-y in the name of "realism".
