If Atlus' Etrian Odyssey III: The Drowned City for the Nintendo DS isn't pretty enough for you, check out Forests of Eternity, the preorder exclusive art book spanning the history of the series. It's much prettier than the game.
I suppose it's not hard for the concept art for a Nintendo DS role-playing series to trump the visuals of the games themselves. The Nintendo DS can only push out so many polys and pixels, after all, and there are no such restrictions for Forests of Eternity.
The book contains 60-pages' worth of full-color artwork, giving us a clear idea of what the artists had in mind before the DS came into play.
Forests of Eternity will be available for pickup with your preordered copies of Etrian III at participating retailers while supplies last, so hopefully your local GameStop isn't staffed by a bunch of video game art fanatics.
