Kind of like Etrian Oddysey? - Mazes of Fate DS
I think q 3 sums it up pretty well. I'd also say that while both games are first person dungeon crawlers, Etrian Odyssey is still for all intents and purposes a JRPG whereas Mazes of Fate comes from the western CRPG lineage. In EO you have turn based, random battles in which you are warped into a "battle screen" mode that is typical of the genre.
