世界樹的迷宮 I・II・III HD REMASTER是由ATLUS推出的經典迷宮探索 RPG 三部曲高清重製合集，收錄系列早期三款作品，並針對現代平台進行全面強化。

於 2023 年 6 月 1 日發售，登陸 Nintendo Switch 與 PC（Steam），內容包含《世界樹的迷宮 HD》、《世界樹的迷宮 II 諸王的聖杯 HD》以及《世界樹的迷宮 III 星海的來訪者 HD》三部作品。

系列核心圍繞著被稱為「世界樹」的巨大地下迷宮展開，每一代都有獨立的故事背景與世界觀。在第一代中，邊境小鎮艾特利亞因為地底出現巨大裂縫而成為冒險者的聚集地，人們為了財富與名聲深入未知的迷宮探索；第二代則將舞台移至海艾拉加德，傳說世界樹頂端存在天空之城，冒險者因此踏上通往天空的旅程；第三代設定在海都阿莫羅德，圍繞沉入海底的古代文明遺跡展開，玩家需要在海洋與地底之間進行雙重探索。

在系統方面，最大的挑戰是將原本 Nintendo DS 雙螢幕設計移植到單螢幕平台，因此重製版加入多種地圖繪製方式。在 Switch 掌機模式下直接觸控繪圖，也可以在電視模式使用搖桿操作來標記地圖，同時新增自動繪圖功能，會自動記錄玩家行走路線與牆壁，大幅降低操作負擔，讓玩家能更專注於戰鬥與探索。

戰鬥與遊玩體驗方面也加入多種難度選擇，包括簡單的 PICNIC、標準的 BASIC，以及保留原始挑戰性的 EXPERT，使新手與老玩家都能找到適合自己的方式。畫面方面全面 HD 化，角色插畫、迷宮場景與怪物圖像皆重新高解析化，音樂則由古代祐三重新編曲，整體臨場感明顯提升，戰鬥特效也更加華麗。

市場評價方面，普遍被認為是誠意十足的重製合集，雖然部分玩家對於失去 Nintendo DS 時期手動繪圖的觸感感到可惜，但更流暢的操作與現代化 UI 仍獲得高度肯定。其中第三代因職業系統與海洋探索內容最為豐富，被認為是整體合集中完成度最高的一作。

整體而言，本作不只是單純的畫質提升，而是針對現代遊戲習慣重新調整後的完整重製版本，至今仍被視為地牢探索 RPG 類型的重要代表作品之一。

Etrian Odyssey I•II•III HD REMASTER is a high-definition remastered compilation of the early trilogy in the dungeon-crawling RPG series developed and published by ATLUS. It brings together the first three mainline entries of the franchise with enhanced visuals, updated systems, and modern platform support for Nintendo Switch and PC (Steam). The collection was released on June 1, 2023.

Each game in the trilogy features a completely independent world and story centered around the mysterious “Yggdrasil” or “World Tree” labyrinth. In the first entry, the frontier town of Etria becomes a hub for adventurers after a massive underground chasm is discovered nearby, drawing explorers seeking fortune and fame into an unknown and dangerous labyrinth. The second entry shifts the setting to High Lagaard, where legends speak of a sky city at the summit of the World Tree, prompting adventurers to climb ever upward into the heavens. The third game takes place in the maritime city of Armoroad, where ruins of an ancient submerged civilization are said to be connected to the World Tree, leading players into a dual exploration of both ocean and dungeon depths.

One of the most significant aspects of the remastered collection is how it adapts the original Nintendo DS dual-screen design to modern single-screen platforms. The game introduces multiple mapping methods, allowing players to draw maps via touch controls in handheld mode or use controller inputs in docked mode. An expanded auto-mapping system also records movement paths and walls automatically, significantly reducing the manual workload while preserving the series’ signature exploration-focused gameplay.

The collection also modernizes difficulty options, offering PICNIC for newcomers, BASIC for standard play, and EXPERT for those who want the original challenging experience. Visually, the games have been fully upgraded to HD, with redrawn character portraits, enhanced environments, and improved monster artwork. The soundtrack has been re-arranged by Yuzo Koshiro, further enhancing immersion, while combat effects have also been improved for greater impact.

In terms of reception, the collection is widely regarded as a faithful and high-quality remaster. While some long-time fans miss the tactile experience of manual map drawing on the DS hardware, the improved interface and smoother gameplay systems are generally praised. The third installment is often highlighted as the strongest entry due to its deeper class system and rich ocean exploration mechanics.

Overall, the collection is considered not just a visual upgrade but a thoughtful modernization of a classic dungeon RPG series, and it remains an important reference point for the genre today.
