A remastered version of the original released for Nintendo Switch and Windows in June 2023 under the title Etrian Odyssey HD.

Drawing comparisons to titles such as Wizardry and The Bard's Tale,[2] Etrian Odyssey challenges players with exploring and mapping a vast dungeon.

The game uses a first-person view to present the dungeon using a combination of relatively simple 3D computer graphics for environments and single-frame 2D sprites for enemies.

The game starts with the player forming an adventuring guild in order to explore the mysterious Yggdrasil Labyrinth from the nearby town of Etria.

He uses the experienced rōnin Ren and the hexer Tlachtga to teach the player how to explore the labyrinth and continue descending into each stratum.

Entering the lowest stratum, they discover the ruins of post-apocalyptic Shinjuku, revealing for the first time that the setting of the game is actually a far-future Earth.

[4] The remastered version is based on the Nintendo DS original instead of its 2013 remake, and includes updated visuals and music, quality of life changes, and additional character portraits.

[18] Atlus' own July 2007 investors report listed US sales of the title at around 30,000 units, roughly 2 months after release.

[6] Although the title was recognized as accomplishing its goals (in terms of presenting a very classic RPG experience), it was noted that this greatly limits its appeal to a certain "hardcore" demographic.

1UP.com summarized this sentiment by concluding "Etrian Odyssey will definitely appeal more to the OCD'd than the ADD'd, and its punishing difficulty and very deliberate pacing may turn off younger gamers who grew up on flashier roleplayers.
