What is best etrian odyssey?

As an AI language model, I do not have personal opinions and cannot provide subjective information about what the "best" Etrian Odyssey game is. However, here are some objective facts about the Etrian Odyssey series:

Etrian Odyssey is a series of dungeon-crawling RPG games developed and published by Atlus. The first game was released for the Nintendo DS in 2007, and since then, several sequels and spin-offs have been released for various platforms.

The games in the series commonly feature a party of customizable adventurers navigating through labyrinthine dungeons, with a heavy emphasis on mapping. Players are usually required to manually draw their own maps on the touch screen of their device, adding a layer of immersion and strategy to the gameplay.

Some of the most well-received games in the series according to game critics and player reviews include Etrian Odyssey II: Heroes of Lagaard, Etrian Odyssey IV: Legends of the Titan, and Etrian Odyssey V: Beyond the Myth. However, as mentioned before, I cannot provide subjective information on which game is the best.
