《瑪利歐&索尼克 at 索契冬季奧運》（日文名：マリオ＆ソニック AT ソチオリンピック，英文名：Mario & Sonic at the Sochi 2014 Olympic Winter Games）是由SEGA開發、任天堂發行的體育競技派對遊戲，於2013年底在Wii U平台獨佔推出。作為「瑪利歐&索尼克奧運系列」的第四款作品，這次的舞台設定在2014年俄羅斯索契冬季奧運會，結合任天堂與SEGA兩大經典角色的跨界合作，並延續其家庭向、多人同樂的特色，強調操作直覺與競技趣味的融合。

不強調傳統的劇情模式，透過多樣化的冬季運動競賽與幻想奧運模式來提供娛樂。操作來自瑪利歐和索尼克系列的多位知名角色，包括瑪利歐、路易吉、碧姬公主、耀西、庫巴，以及索尼克、塔爾斯、納克魯斯、艾咪、蛋頭博士等共20名以上的角色，參加不同的冬季項目比賽，如花式滑冰、滑雪、冰球、雪橇等。每位角色都根據其個性與身形特點有著不同的速度、力量與技巧屬性，進一步影響比賽結果。

操作方面，多數項目支援Wii Remote Plus與Nunchuk操作，透過體感控制進行模擬運動，例如揮動手臂模仿滑雪動作、轉動控制器來轉彎、或是按時機揮動來完成花式滑冰的特技。部分項目也支援Wii U GamePad操作，尤其在幻想奧運（Dream Events）中，GamePad用作特殊介面，如觸控控制雪車、俯瞰地圖操作，甚至在迷你遊戲中模擬競技場視角。這些設計雖然並非每一項都完全準確或順手，但整體增添互動趣味與體感遊戲的多元化。

幻想奧運是本作的一大特色，現實運動與瑪利歐與索尼克世界觀中的奇幻元素結合。例如在夢幻冰壺中，不僅要擊打冰壺，還能使用道具妨礙對手；夢幻滑雪競速則像瑪利歐賽車一樣，玩家可使用龜殼、加速器等經典道具進行激烈競爭。這些模式相較於正規比賽更加強調遊戲性與創意，吸引不只運動迷，亦讓喜愛派對遊戲的玩家投入。

在多人模式方面，支援本地最多四人同機遊玩，是家庭與朋友聚會時的熱門選擇。雖然也具備線上排行榜與部分對戰功能，但整體而言，線上互動並非主打重點。亦收錄每日挑戰與訓練模式，鼓勵玩家重複挑戰與進步。

市場評價方面，在發售後獲得中等至正面的評價。許多評論肯定它的畫面表現相較前作有明顯提升，角色建模細緻、場景色彩鮮明，符合奧運會歡樂與節慶的氛圍。Nintendo Life給出7/10的評價，認為遊戲在派對性與角色魅力上表現優異，適合闔家歡樂的遊玩環境。然而也有評論指出，部分比賽項目操作不夠直覺，尤其是體感控制的準確度不一，可能造成某些比賽體驗不如預期。另外，有玩家反映本作缺乏豐富的單人內容，若無法常與他人遊玩，重玩性較低。

總體來說，《瑪利歐&索尼克 at 索契冬季奧運》針對家庭玩家與派對場景設計，成功將任天堂與SEGA經典角色融合在奧運競技之中，並透過Wii U的硬體特性強化互動樂趣。雖然在操作精度與單人深度方面仍有不足，但作為聚會娛樂或喜歡冬季運動題材的遊戲愛好者，提供豐富又歡樂的體驗。

Mario & Sonic at the Sochi 2014 Olympic Winter Games (Japanese title: マリオ＆ソニック AT ソチオリンピック) is a sports party game developed by SEGA and published by Nintendo, released exclusively for the Wii U in late 2013. As the fourth installment in the Mario & Sonic at the Olympic Games series, this title is set during the 2014 Winter Olympics in Sochi, Russia, and continues the crossover collaboration between two of gaming’s most iconic franchises—Nintendo’s Mario and SEGA’s Sonic the Hedgehog. It retains the series’ focus on accessible controls and multiplayer fun, making it ideal for family entertainment and party settings.

Rather than featuring a traditional story mode, the game delivers its entertainment through a wide variety of winter sports events and fantasy-themed competitions called Dream Events. Players can choose from over 20 familiar characters drawn from both the Mario and Sonic universes, such as Mario, Luigi, Princess Peach, Yoshi, Bowser, Sonic, Tails, Knuckles, Amy, and Dr. Eggman. Each character has unique stats—such as speed, power, and technique—that influence their performance in different events like figure skating, skiing, ice hockey, and bobsledding.

In terms of gameplay, most events support the Wii Remote Plus and Nunchuk for motion-based controls. Players mimic real-world movements—such as swinging arms to simulate skiing, tilting the controller to steer, or timing gestures to execute figure skating tricks. Some events also utilize the Wii U GamePad, especially in the Dream Events. In these, the GamePad might serve as a touchscreen control device for bobsled steering, a map interface for navigation, or a dynamic viewpoint in mini-games. While not all motion controls are equally precise, the variety adds to the game’s interactive charm and diversity of playstyles.

One of the game’s standout features is the Dream Events mode, where real-world Olympic sports are combined with fantastical elements from the Mario and Sonic universes. In Dream Curling, for example, players not only slide stones but also use items to sabotage opponents. Dream Ski Cross resembles Mario Kart, where players can use classic power-ups like shells and speed boosts to compete in fast-paced races. These fantasy modes emphasize creativity and fun over realism, appealing to casual and party gamers who may not be traditional sports fans.

Multiplayer support is a major strength of the game. Up to four players can compete locally, making it a popular choice for gatherings and family game nights. While the game includes some online features such as leaderboards and limited competitive play, online interaction is not the main focus. The inclusion of daily challenges and training modes helps encourage replayability, even for solo players.

Critically, the game received mixed to positive reviews. Many praised the improved visuals over previous entries, noting detailed character models and colorful environments that reflect the festive spirit of the Olympics. Nintendo Life gave it a 7/10, highlighting its charm, party appeal, and strong character roster. However, some criticisms were aimed at inconsistent control responsiveness, particularly in motion-controlled events, which could affect the gameplay experience. Additionally, the limited depth in solo content meant that players without regular access to local multiplayer might find less reason to return frequently.

Overall, Mario & Sonic at the Sochi 2014 Olympic Winter Games is a vibrant, family-oriented title that successfully blends Nintendo and SEGA’s beloved characters with the excitement of Olympic sports. While it may fall short in precision control and solo depth, its joyful presentation, accessible gameplay, and multiplayer focus make it a worthwhile experience for party game enthusiasts and fans of winter sports alike.
