《永恆深藍》（英文名稱：Forever Blue/Endless Ocean，日文名稱：フォーエバーブルー）是由Arika開發、任天堂發行的Wii專屬潛水模擬遊戲，於2007年在日本和北美上市。非傳統意義上的冒險或動作遊戲，而是以海洋探索與生態觀察為核心的慢節奏作品。玩家將扮演一位潛水員，搭乘潛水艇來到虛構的南太平洋珊瑚礁海域“Manoa Lai”島嶼，展開充滿療癒氛圍的水下之旅。由於其獨特的非競技性玩法與優美的自然場景，該作在Wii遊戲陣容中占有特殊地位。

遊沒有明確的劇情主線，也幾乎沒有傳統意義上的任務推進系統。目標是探索海底世界、觀察並紀錄各種海洋生物（從熱帶魚到巨型海洋哺乳類），蒐集資訊並建構屬於自己的「海洋圖鑑」。透過與海洋生物的互動，逐漸解鎖更多潛水地點，包括沉船遺跡、深海溝、海底洞窟等特殊場景，每個地區都有其獨特的生態系統與隱藏要素。雖然整體敘事簡略，但在潛水船上與女助手Katherine的互動中，偶爾會穿插些微的敘事線，例如幫助研究機構、回收海底遺物或照顧生病的動物，為整體探索過程帶來溫柔的人文色彩。

在操作方面，用直覺方式體驗潛水的臨場感。使用Wii遙控器指向螢幕來控制潛水員的游泳方向，按鈕則負責下潛、上浮與互動。當靠近特定生物時，可以按下按鍵進行觀察、餵食或發出聲音吸引牠們的注意。這些互動不僅增添遊戲趣味，也有助於蒐集資料完成圖鑑。支援單人模式，也能透過WiiConnect24分享照片給朋友，甚至使用SD卡保存水下攝影作品。整體操作簡單直觀，且沒有時間限制或氧氣限制，強調自由與沉浸感，帶給「純粹放鬆」的遊戲體驗。

畫面方面，雖然受到Wii主機硬體性能限制，但在視覺呈現上仍達到令人驚艷的水準。海水的透明度、光影變化、魚群游動的自然動態都經過細緻打造，營造出靜謐且具有深度的海洋空間。海底場景具備豐富多變的視覺層次，從五彩斑斕的珊瑚礁到陰暗的深海裂縫，每個區域都有不同的氛圍與探索驚喜。配樂方面選用眾多新世紀音樂與環境音樂曲目，例如Enya的音樂，加強療癒與冥想的感受。整體美術與聲音設計共同營造出一種「沉浸式冥想」的氛圍，讓人幾乎忘卻時間流逝。

在市場評價方面，獲得整體正向但兩極化的回應。對於喜歡自然、生態與慢節奏體驗的玩家來說，是極具療癒效果的珍品。IGN給予8.0分，讚賞其獨特主題與圖像氛圍，認為是「Wii上最放鬆的遊戲之一」。GameSpot則給出7.6分，肯定其美術與環境設計，但也指出缺乏挑戰性與重玩動力，對於傳統玩家而言可能過於單調。日本的《Famitsu》則給出31/40的分數，認為其氛圍營造與角色互動溫馨動人，但也批評內容深度稍嫌不足，若非生態愛好者可能難以長期投入。即便如此，仍建立一群忠實的粉絲，並促成2009年推出的續作《永恆深藍：深海探索》（Forever Blue: Call of the Ocean）。

總結來說，《永恆深藍》是罕見地將遊戲作為「冥想體驗」來設計的作品。不靠競爭、不靠劇情高潮，而是透過寧靜優雅的方式，引導玩家在廣闊海底世界中慢慢地觀察、學習與欣賞。對於尋求平靜心靈、喜愛自然生態或期待與家人共享一段悠閒時光的玩家而言，是極具魅力的選擇。

Forever Blue (known in English as Forever Blue or Endless Ocean, and in Japanese as フォーエバーブルー) is a scuba diving simulation game developed by Arika and published by Nintendo exclusively for the Wii. Released in 2007 in Japan and North America, the game stands out from traditional adventure or action titles by offering a slow-paced experience centered on marine exploration and ecological observation. Players take on the role of a diver arriving at the fictional coral reef island of Manoa Lai in the South Pacific, embarking on a tranquil underwater journey. Thanks to its non-competitive gameplay and beautifully rendered natural environments, Forever Blue occupies a unique position in the Wii’s library.

The game does not follow a conventional narrative or mission-based structure. Instead, players are encouraged to freely explore the ocean, observe and catalog a wide array of sea creatures—ranging from tropical fish to massive marine mammals—and gradually build their own marine encyclopedia. Through interactions with marine life, new diving areas are unlocked, such as sunken ships, deep-sea trenches, and underwater caves, each with its own ecosystem and hidden details. While the overall story is minimal, occasional narrative elements surface through conversations with your assistant Katherine aboard the diving boat. These may involve aiding research efforts, recovering underwater relics, or caring for injured animals, adding a gentle human dimension to the exploration experience.

In terms of gameplay, Forever Blue offers an intuitive, immersive diving experience using the Wii Remote. Players point the controller at the screen to guide the diver’s movement and use buttons to dive, ascend, or interact with objects and creatures. When approaching marine animals, players can choose to observe them, feed them, or emit sounds to draw their attention. These interactions are both engaging and crucial for completing the marine encyclopedia. The game supports single-player mode and allows players to share underwater photos with friends via WiiConnect24 or save them on an SD card. There is no time limit or oxygen gauge, emphasizing complete freedom and immersion, and offering a purely relaxing gameplay experience.

Visually, Forever Blue achieves impressive results despite the hardware limitations of the Wii. The water’s clarity, realistic lighting, and natural movement of sea life are rendered with care, creating a peaceful and immersive undersea environment. The underwater scenery is richly varied, from colorful coral reefs to dark, mysterious ocean fissures, with each area offering its own ambiance and surprises. The soundtrack features a selection of new-age and ambient tracks, including music by Enya, which enhances the meditative and healing tone of the game. The combination of art and sound design fosters a deeply immersive, almost “meditative” experience that allows players to lose track of time.

Reception of Forever Blue was generally positive but somewhat polarized. For players who enjoy nature, ecology, and slower-paced gameplay, it became a rare and soothing gem. IGN gave it an 8.0, praising its unique theme and atmospheric visuals, calling it “one of the most relaxing games on the Wii.” GameSpot rated it 7.6, applauding the aesthetics and environmental design but also noting its lack of challenge and replay incentive, which may feel too monotonous for more traditional gamers. Japan’s Famitsu scored it 31 out of 40, highlighting the warm atmosphere and character interaction while noting the limited gameplay depth—potentially a drawback for those not inherently drawn to ecological themes. Nevertheless, the game garnered a devoted fanbase and led to the release of a sequel in 2009: Forever Blue: Call of the Ocean.

In summary, Forever Blue is a rare example of a game designed as a “meditative experience.” It forgoes competition and dramatic storytelling in favor of quiet, graceful engagement with the natural world. For players seeking inner peace, an appreciation for marine life, or a calm, shared moment with family, it remains a uniquely captivating choice.
