Atlus has released a trailer for the upcoming Etrian Odyssey 3, featuring glimpses of both gameplay and new classes. The trailer highlights the addition of ships to the series, but the game mechanics on the high seas look to be strikingly similar to those in the dungeon. Judging from the trailer, Etrian Odyssey 3 does not appear to be a radical departure from its predecessors, but the traditional aspects of Etrain Odyssey are what keep the dedicated fans coming back for more.
