《涼宮春日的並列》（日文原名：涼宮ハルヒの並列）是基於人氣輕小說與動畫系列《涼宮春日的憂鬱》所改編的Wii專屬遊戲，由Banpresto開發，於2009年在日本地區發行。延續《涼宮春日》宇宙的世界觀，設定時間在動畫第一季與第二季之間，強調角色互動與日常推進，並以輕鬆歡樂的氣氛包裝一連串迷你遊戲與劇情片段，帶出「非日常」中的日常感。這款遊戲主要面向系列粉絲，試圖以體感操作的方式重現《涼宮》世界的獨特魅力。

劇情採用原創路線，背景設在北高文化祭前夕，涼宮春日為讓SOS團的攤位成為校園話題，決定開發可以吸引群眾的「攤位遊戲大集合」。於是，她命令阿虛、長門有希、朝比奈實玖瑠與古泉一樹各自分頭設計遊戲內容，將以阿虛的視角，參與開發與測試過程。隨著劇情推進，不僅能探索學校各個場景與角色互動，還會逐步揭露關於涼宮無意識能力所引發的奇異現象，例如時間循環、空間異常與神祕NPC出現等，延續原作中的「超自然但無人自知」設定。

操作方面，因為是結合視覺小說元素與大量迷你遊戲的冒險作品。在劇情模式中，透過選擇對話、場景探索來推進事件，有如閱讀互動小說。真正的體感元素則集中在迷你遊戲部分，多半以涼宮團員為主角開發，內容包含音樂節奏、記憶配對、反應挑戰、射擊遊戲、料理遊戲、卡牌對戰等，形式多元。每種遊戲皆使用Wii遙控器進行操作，例如揮動手臂、指向螢幕、按下節奏點等，有些則需配合角度或動作節奏，模擬特定任務過程。雖然這些遊戲偏向簡單，但在設定與演出上充滿《涼宮》風格，例如「長門的資料侵入遊戲」或「春日的舞台演出指導」等，能感受角色個性的同時，參與獨特活動。

視覺方面延續動畫風格，角色設計與立繪由原動畫人設伊東雋一繪製，搭配全語音演出，讓人彷彿置身於動畫世界之中。場景重現度高，包括教室、走廊、社團活動室等均貼近原作。過場動畫與表情動態也配合角色情緒變化，使每段對話具備豐富臨場感。音樂方面使用動畫配樂為基礎，並新增多首原創BGM與主題曲，整體氣氛時而搞笑、時而神秘，符合系列基調。

市場評價方面，獲得粉絲間的普遍肯定，特別是對角色還原度與聲優表現給予正面評價。成功重現原作的「角色互動魅力」，並透過Wii主機提供全語音、互動性的娛樂體驗。不過也有評論指出遊戲整體難度偏低，迷你遊戲重複性高、缺乏深度與挑戰性，對非原作粉絲來說吸引力不足。此外劇情主線過於分散，若不熟悉涼宮宇宙，容易對其中的超自然暗示與人物背景感到迷惘。

總結來說，這是專為《涼宮》系列粉絲設計的Wii互動遊戲，以視覺小說敘事結合體感小遊戲重現角色間的趣味互動與青春日常。雖然其玩法偏向輕量級，操作設計也非特別創新，但以角色魅力與動畫還原度為核心賣點，成功營造出讓人與SOS團共度文化祭準備期的「非日常體驗」。對於喜歡涼宮春日或日系角色劇情遊戲的玩家來說，是充滿粉絲服務與懷舊感的作品。

The Parallel of Haruhi Suzumiya (Japanese title: 涼宮ハルヒの並列) is a Wii-exclusive game based on the popular light novel and anime series The Melancholy of Haruhi Suzumiya. Developed by Banpresto, it was released in Japan in 2009. Continuing the world of the Haruhi Suzumiya universe, the game is set between the first and second seasons of the anime, emphasizing character interactions and daily life progression. Wrapped in a cheerful and lighthearted atmosphere, it presents a series of mini-games and story episodes that capture the "extraordinary within the ordinary." Primarily aimed at fans of the series, it strives to recreate the unique charm of Haruhi Suzumiya through motion-controlled gameplay.

The story follows an original scenario set just before the North High School cultural festival. To make the SOS Brigade’s booth the talk of the school, Haruhi Suzumiya decides to create a collection of crowd-pulling "booth games." She assigns Kyon, Yuki Nagato, Mikuru Asahina, and Itsuki Koizumi to individually design game concepts. Players, taking on Kyon’s perspective, participate in the development and testing process. As the story progresses, players can explore various areas of the school and interact with characters, while uncovering bizarre phenomena inadvertently caused by Haruhi's unconscious powers — such as time loops, spatial distortions, and mysterious NPC appearances — in line with the original series' "supernatural events unnoticed by most" theme.

In terms of gameplay, it blends visual novel elements with a large number of mini-games. During story segments, players advance the plot through dialogue choices and scene exploration, akin to reading an interactive novel. The motion controls come into play mainly during the mini-games, which were "developed" by each SOS Brigade member. These mini-games span a variety of genres, including rhythm games, memory matching, reflex challenges, shooting games, cooking games, and card battles. Each uses the Wii Remote for intuitive actions like swinging the arm, pointing at the screen, or timing button presses. Some games also require players to tilt or move the controller rhythmically to simulate specific tasks.
While the mini-games are generally simple, they are packed with the distinct personality of the Haruhi universe — for example, Yuki’s data hacking game or Haruhi’s stage performance rehearsal — allowing players to engage in activities that reflect each character’s traits.

Visually, the game retains the anime’s art style, with character designs and illustrations by Noizi Ito, the original anime character designer. The game features full voice acting, making it feel like stepping directly into the anime world. Familiar locations such as classrooms, hallways, and club rooms are faithfully recreated. Cutscenes and character expressions change dynamically with the dialogue, adding rich emotional depth to each interaction.
Musically, the soundtrack draws from the anime's compositions while adding several original background tracks and a new theme song, keeping the atmosphere lighthearted, occasionally mysterious, and true to the spirit of the series.

In terms of reception, the game was well-received among fans, especially for its faithful character portrayals and the strong performances by the voice actors. It successfully captures the "charm of character interactions" that defines the series, offering a full-voice, interactive entertainment experience through the Wii. However, some critics noted that the overall difficulty is quite low, the mini-games can feel repetitive, and the lack of depth and challenge may make it less appealing to those unfamiliar with the franchise. Additionally, the story is somewhat scattered, and players not versed in the Haruhi universe might find the supernatural hints and character backgrounds confusing.

In summary, The Parallel of Haruhi Suzumiya is a Wii interactive game designed specifically for fans of the Haruhi series. Combining visual novel storytelling with motion-controlled mini-games, it recreates the lively interactions and youthful daily life of the SOS Brigade. While the gameplay leans toward the lightweight and the controls are not particularly innovative, the focus on character charm and faithful anime reproduction makes it a successful "extraordinary experience" of preparing for the cultural festival alongside Haruhi and friends. For fans of Haruhi Suzumiya or Japanese character-driven story games, it offers a nostalgic, fan-service-filled journey.
