If you read my preview of Etrian Odyssey III: The Drowned City, then you know that building your team is a big part of the game. Atlus PR maestro Aram Jabbari goes into greater detail in this new trailer, explaining the strengths and weaknesses of each class and how you can specialize in sub-fields. Etrian III launches September 21st, and keep in mind that if you pre-order, you get a beautiful 60 page artbook that covers the entire Etrian series.
