《超級瑪利歐銀河2》（Super Mario Galaxy 2 / スーパーマリオギャラクシー 2）是任天堂於2010年在Wii平台推出的3D動作平台遊戲，由宮本茂監製，EAD東京開發團隊負責，是2007年大獲好評的《超級瑪利歐銀河》的正統續作。本作延續前作以「宇宙」作為冒險舞台的設定，同時在關卡設計、操作內容以及遊戲節奏上全面進化，堪稱Wii平台最具代表性與技術完成度的作品之一。

劇情方面，沿襲瑪利歐系列一貫的冒險救公主情節。碧姬公主再度被庫巴綁走，而這次的庫巴吸收神秘宇宙力量，變得巨大且更加兇猛。瑪利歐必須在星星精靈露比（Lubba）的幫助下，搭乘飛行星球「星星飛船瑪利歐號」，前往不同的銀河世界，蒐集能量之星，挑戰庫巴並救回碧姬公主。儘管劇情本身依舊簡單直觀，但透過每個銀河世界獨特的主題與演出，營造出豐富的幻想氛圍，搭配可愛角色互動與流暢動畫，使整體冒險過程極具故事性與吸引力。

在操作方面，沿用Wii遙控器與Nunchuk的雙手分離操作方式，以遙控器控制鏡頭視角、發射星星碎片並鎖定敵人，以Nunchuk操控瑪利歐移動，並透過搖動遙控器進行旋轉攻擊與跳躍動作。系統操作回饋流暢且手感扎實，尤其在3D空間跳躍與重力反轉的過關設計下，操作精準度與節奏感更顯重要。新加入的耀西系統是本作最大特色之一，特定關卡中可騎乘耀西，不但能使用舌頭捕捉敵人與道具，還能藉由吃下不同水果獲得特殊能力，例如閃電耀西可高速衝刺、氣球耀西可漂浮，為操作與戰鬥方式增添更多變化。

關卡設計是最受讚譽的部分。全作共分為六大世界、數十個銀河，每個銀河擁有截然不同的主題與機關設計，從重力顛倒的星球、熔岩環繞的火山、音樂節奏關卡、冰雪世界，到空中浮島與太空軌道，每一關幾乎都帶來全新的玩法概念與挑戰手法。關卡中隱藏許多秘密星星與隱藏通道，鼓勵玩家探索與嘗試。相比前作，節奏更加明快，機關設計也更加刁鑽刺激，充分發揮Wii的體感操作與3D重力系統特色。此外，部分關卡還加入時間挑戰、連續敵人討伐與特殊條件過關等多樣目標，提升遊戲耐玩度。

在市場評價方面，獲得壓倒性好評，IGN、GameSpot、Eurogamer等國際媒體皆給予極高分數。IGN更給出10分滿分，稱讚其「無懈可擊的關卡設計、絕佳的操作手感與視覺表現」，認為是「任天堂創意巔峰的證明」。玩家普遍認為本作在延續前作優秀基礎上，大幅提升遊戲節奏與挑戰強度，耀西系統的加入亦為玩法注入新鮮感。視覺表現方面，Wii硬體雖然有限，但透過優異的美術設計、鮮豔的配色與極具想像力的星球造型，使整體畫面表現超越當時平台水準。音樂方面，沿用大量現場錄製交響樂曲，搭配宇宙主題，營造磅礡且夢幻的聽覺體驗。

總結來說，這不僅是瑪利歐系列在Wii時代的集大成之作，更是3D平台動作遊戲範疇中的經典範例。它兼具創意、操作樂趣與高完成度，無論是對系列老玩家，或是首次接觸的入門者，皆能在這片浩瀚宇宙中，體驗純粹的遊戲冒險魅力。

Super Mario Galaxy 2 (スーパーマリオギャラクシー 2) is a 3D action-platformer developed by Nintendo and released for the Wii in 2010. Produced by Shigeru Miyamoto and developed by the EAD Tokyo team, it is the direct sequel to the critically acclaimed Super Mario Galaxy (2007). Building upon the cosmic adventure setting of its predecessor, the game pushes the boundaries further in level design, controls, and pacing, and is considered one of the most technically refined and iconic titles on the Wii platform.

In terms of story, it follows the familiar Mario series formula of rescuing Princess Peach. This time, Peach is once again kidnapped by Bowser, who has absorbed mysterious cosmic powers and grown to enormous size and strength. With the help of a star creature named Lubba, Mario boards the “Starship Mario” and journeys across various galaxies to collect Power Stars, confront Bowser, and save Peach. Though the narrative remains simple and straightforward, each galaxy features unique themes and cinematic presentation, creating a whimsical, storybook atmosphere. Charming character interactions and fluid animations enhance the storytelling appeal throughout the adventure.

Gameplay-wise, it retains the dual-handed Wii Remote and Nunchuk control scheme. Players use the Wii Remote to aim the camera, shoot Star Bits, and lock onto enemies, while the Nunchuk controls Mario’s movement. Shaking the remote allows Mario to perform spin attacks and jumps. The controls feel smooth and responsive, and precise timing becomes even more critical in stages featuring complex gravity shifts and platforming challenges. One of the most notable additions is the introduction of Yoshi. In specific levels, Mario can ride Yoshi, who uses his tongue to grab enemies and items. Eating different fruits grants Yoshi special abilities—such as the Dash Pepper for speed bursts or the Blimp Fruit for floating—adding new layers of variety to both combat and traversal.

Level design is one of the game’s most celebrated elements. Divided into six main worlds containing dozens of galaxies, each galaxy presents a fresh and distinct concept—from gravity-flipping planets and volcanoes surrounded by lava, to rhythm-based levels, icy landscapes, floating islands, and cosmic railways. Nearly every level introduces new mechanics and creative gameplay twists. Hidden stars and secret paths are scattered throughout, encouraging players to explore and experiment. Compared to its predecessor, the game offers faster pacing and more intricate mechanisms, making excellent use of the Wii’s motion controls and the game’s gravity-based systems. Some stages also include time trials, enemy gauntlets, and special condition challenges, significantly enhancing the game’s replayability.

Reception-wise, Super Mario Galaxy 2 received overwhelming critical acclaim. IGN awarded it a perfect 10/10, praising its “flawless level design, superb controls, and stunning visuals,” calling it “proof of Nintendo’s creative peak.” Reviewers and players alike felt the game improved upon its predecessor’s foundation by elevating the challenge and pacing, while the Yoshi mechanic introduced a refreshing twist. Visually, despite the Wii’s hardware limitations, the game surpasses expectations through vibrant art direction, imaginative planetary designs, and bold color palettes. Its visuals often rivaled those of more powerful platforms of its time.

The music remains another standout feature, featuring a rich orchestral soundtrack recorded with live musicians. It continues the series’ tradition of dramatic and whimsical compositions, perfectly complementing the grand scale and fantastical tone of the game’s universe.

In conclusion, Super Mario Galaxy 2 is not only a culmination of the Mario series on the Wii, but also a benchmark in the genre of 3D platformers. With its blend of creativity, refined gameplay, and high production value, it offers an unforgettable space-faring adventure. Whether you’re a longtime fan or a newcomer to the series, the game delivers pure platforming joy and stands as an essential experience in gaming history.
