Etrian Odyssey review at Nintendo World Report.

"When you power up the DS with Etrian Odyssey (EO) on board, you're greeted with a rather nice looking rendering of a tree in a clearing spanning both screens. As the game starts out, the excellent art, music and production values immediately indicate that EO is a work of significant quality. Then you step into the forest and spend an hour drawing a map of the first floor on the touch screen, after which you may be annihilated by a few poisonous butterflies. Yes, Etrian Odyssey is the very definition of old-school gaming. Even so, after about 10 hours (only 20% of the game) I had gotten the hang of things and was quite impressed and rather hooked. I thought, "If they keep the fresh gameplay coming and don't recycle too much of the excellent art, this will be a great game for a certain kind of gamer." While EO does falter just a tad, it keeps things quite entertaining given its considerable length."
