2006年9月28日在日本上市的DS遊戲《寶可夢 鑽石／珍珠》（ポケットモンスター ダイヤモンド・パール），由Game Freak負責製作。在2021年1 1月19日重製的版本《寶可夢 晶燦鑽石／明亮珍珠》則移植到Switch平台。全球銷售量超過1700萬套，是2007年的最暢銷遊戲。登場的所有寶可夢數量有493隻，初期只能依照圖鑑尋找151隻寶可夢，最後拿到全國圖鑑才能調查所有的寶可夢。選擇性別後就可展開冒險，另一位沒有選上的人物之後會變成競爭對手。

故事描述在擁有許多天然資源的「神奧地區」，是以現實世界中的北海道為藍本，擁有豐富多樣的自然景觀與地形，從冰雪覆蓋的山脈到茂密的森林應有盡有。玩家會在湖畔旁邊發現博士所遺留下來的手提箱，為收集完整的寶可夢圖鑑，一場冒險就此展開。需要持續培養出強大的寶可夢，然後向每個城市的道館館主進行挑戰，每次獲得勝利會取得徽章。收集八個以後就可以挑戰神奧區內的四天王跟最終的冠軍。

在神奧地區中央有長年被白雪覆蓋的聖山「天冠山」，會碰到許多攻擊力極強的寶可夢。當沿路移動的時候，會有真實的白天跟夜晚的變化。不同的時段，出現的野生寶可夢也不一樣，而商店內的商品也會變動。有一些寶可夢需要用釣竿才能釣到或是用「甜甜蜜」塗抹在一些樹上，如果樹木搖晃得相當劇烈，可能會有相當稀有的寶可夢出現。

這次登場的反派是「銀河隊」，會對玩家進行騷擾以外，還會到處濫抓寶可夢。他們的目的是利用傳說中的寶可夢，企圖改變世界的規則，創造一個符合其理念的新世界。需要與他們對抗，揭開背後的陰謀，並最終阻止他們操控神秘傳說中的寶可夢—帝牙盧卡（Dialga），這隻寶可夢掌握著時間的力量，是整個遊戲中最具神話色彩的角色之一。

在操作方面，沿用系列傳統的回合制戰鬥系統，攜帶最多六隻寶可夢進行戰鬥。每隻寶可夢都有不同的屬性和技能，戰鬥中要根據敵人的屬性，運用策略來選擇合適的寶可夢和技能。還引入現代寶可夢遊戲中的一些便捷功能，例如自動經驗分享系統，讓整個隊伍都能在戰鬥後獲得經驗，這大大簡化培養寶可夢的過程。此外，透過寶可夢中心進行網絡對戰或交換寶可夢，與世界各地的玩家互動。

作為重製版，關卡設計與原版大體一致，但進行多方面的改良。例如，原作中的「地下世界」被重新設計為「地下大洞窟」，不僅保留挖掘化石和寶藏的系統，還新增「寶可夢棲地」，在這些特定區域遇到許多不同種類的寶可夢，甚至包括一些稀有的精靈。這讓探索地下世界變得更加豐富多彩。還恢復粉絲喜愛的「超級華麗大賽」，帶著自己精心培育的寶可夢參加競賽。

市場評價方面，收到褒貶不一的反應。許多玩家對於遊戲的畫面升級和懷舊元素感到滿意，尤其是經典的神奧地區重新以高清形式呈現，給老玩家帶來強烈的情感共鳴。音樂也得到好評，對原作配樂進行重新編排，增添現代感，但仍保留了原有的氛圍。

然而，部分玩家對於遊戲的創新不足感到失望。重製版在遊戲系統和內容上沒有太多顯著變化，對於已經熟悉原版遊戲的老玩家來說，可能會感到缺乏挑戰和新鮮感。此外，畫面的「Q版」角色設計風格也引起爭議，有些玩家認為這種設計顯得過於簡單，未能充分發揮Switch主機的圖形潛力。

遊戲中有三隻傳說的寶可夢，分別為知識之神「由克希」、感情之神「艾姆利多」、 意志之神「亞克諾姆」。鑽石版跟珍珠版的差異在於鑽石有掌管時間的「帝牙盧卡」，寶可夢有臭鼬噗、頭蓋龍等。珍珠版則是有掌管空間的「帕路奇亞」，寶可夢則有魅力喵、盾甲龍等。兩種版本的寶可夢出現機率設定及圖鑑說明內容也不一樣。 

The 2006 DS game Pokémon Diamond and Pearl (ポケットモンスター ダイヤモンド・パール) was developed by Game Freak and released in Japan on September 28, 2006. The remade versions, Pokémon Brilliant Diamond and Shining Pearl, were ported to the Switch platform and launched on November 19, 2021. With global sales surpassing 17 million units, it was the best-selling game of 2007. The game features a total of 493 Pokémon, but initially, players can only find 151 according to the Pokédex. The full roster of Pokémon becomes available once players obtain the National Pokédex. After choosing the player's gender, the adventure begins, and the character not chosen becomes the player's rival.

The story takes place in the Sinnoh Region, which is rich in natural resources and modeled after the real-world Hokkaido. The region boasts diverse landscapes, ranging from snow-covered mountains to dense forests. The player's adventure starts after discovering a briefcase left behind by a professor by the lakeside. The goal is to complete the Pokédex by collecting and training powerful Pokémon, all while challenging Gym Leaders in various cities. After obtaining all eight Gym Badges, players can challenge the Sinnoh Elite Four and eventually the Champion.

At the heart of the Sinnoh Region lies Mt. Coronet, a sacred mountain that is perpetually covered in snow and home to many powerful Pokémon. As players explore, they experience real-time changes between day and night. Different Pokémon appear depending on the time of day, and the items available in shops also change. Certain Pokémon can only be encountered by fishing or using "Honey" on trees. If a tree shakes violently, a rare Pokémon may appear.

The game's villains, Team Galactic, not only harass the player but also capture Pokémon indiscriminately. Their ultimate goal is to harness the power of legendary Pokémon to rewrite the rules of the world and create a new universe aligned with their vision. Players must confront them, uncover their plot, and prevent them from controlling the legendary Pokémon Dialga, who holds the power of time and is one of the most mythical figures in the game.

In terms of gameplay, it retains the traditional turn-based battle system of the series. Players can carry up to six Pokémon in battle, each with its own attributes and moves. Strategy is key, as players must select Pokémon and moves based on the opponent’s type. Modern features, such as the Experience Share system, allow the entire team to gain experience after battles, significantly simplifying the training process. Players can also engage in online battles or trade Pokémon with others through the Pokémon Center, interacting with players worldwide.

As a remake, the level design remains mostly faithful to the original but with several improvements. For instance, the original Underground system has been redesigned as the Grand Underground. While it retains the fossil-digging and treasure-hunting mechanics from the original game, it introduces Pokémon Hideaways, where players can encounter a wide variety of Pokémon, including some rare species. This makes exploring the underground world more engaging. The fan-favorite Super Contest Shows also make a return, allowing players to showcase their meticulously raised Pokémon in competitions.

In terms of market reception, the game received mixed reviews. Many players praised the upgraded graphics and nostalgic elements, especially the high-definition recreation of the Sinnoh Region, which evoked strong emotional connections for long-time fans. The remastered music was also well-received, blending modern updates with the original atmosphere.

However, some players were disappointed by the lack of innovation. The remake didn’t introduce many significant changes to the gameplay systems or content, which left some veteran players feeling that it lacked challenge and freshness. Additionally, the "chibi" character design sparked controversy, as some felt that the simplified art style didn’t fully utilize the graphical potential of the Switch.

There are three legendary Pokémon in the game: Uxie (the deity of knowledge), Mesprit (the deity of emotion), and Azelf (the deity of willpower). The key difference between Diamond and Pearl lies in the version-exclusive Pokémon. In Diamond, players encounter Dialga, the Pokémon that controls time, as well as species like Stunky and Cranidos. In Pearl, the legendary Pokémon is Palkia, who controls space, and version-specific species include Glameow and Shieldon. The encounter rates and Pokédex entries also differ between the two versions.
