《怪獸卡車4x4 世界賽車廠》（Monster 4x4: World Circuit，日文名《モンスター4×4 ワールドサーキット》）是Ubisoft於2006年發行的賽車遊戲，也是Wii主機早期發售的第三方作品之一。最大賣點是強調體感操作，並試圖結合誇張風格的越野競速體驗與派對式的遊戲設計，特別針對家庭與休閒玩家市場。

以世界賽道巡迴為主軸，駕駛大型怪獸卡車—這種改裝過的四輪巨型車輛擁有異常高的懸吊與強勁馬力——參與全球多個極端地形的賽事。雖然並無明確的劇情敘述或角色故事，但其賽事安排與風格意圖傳達一種環遊世界、征服極限地形的冒險精神。從撒哈拉沙漠到冰封極地，從古文明遺址到城市賽道，每個場景都以明亮、誇張的卡通風格呈現，營造出輕鬆而熱鬧的賽車氛圍。

在操作方面，充分利用Wii Remote的體感功能。將遙控器橫握模擬方向盤，透過傾斜控制方向，並搭配按鈕進行加速、煞車與跳躍等操作。有許多跳躍平台、特技彎道與障礙物，執行各種誇張動作來獲取加速（turbo）或分數獎勵。某些賽道甚至設有環形軌道與垂直跳躍設計，使整體遊玩節奏更具動態感。

還提供道具攻擊系統，類似於《瑪利歐賽車》系列。在賽道上收集道具，用於攻擊對手或防禦，例如火箭、油漬、或加速器，增加比賽的不確定性與刺激感。此外，支援本地多人模式，最多可四人分屏競速，也有時間試煉與特技挑戰等額外模式，旨在提升遊戲耐玩度。

然而，在發售後的市場評價多為中下，尤其在專業媒體間評價普遍不高。評論普遍認為雖有趣味設定與體感操作的創新企圖，但整體內容粗糙、畫面表現過於簡單，尤其在與Wii同期競品如《Excite Truck》相比時顯得技術落後。物理引擎缺乏真實感，操作手感有時過於飄浮或反應延遲，使部分玩家在高速行駛或特技操控時感到不協調。

玩家社群則對此遊戲反應兩極。一方面，有家庭與年幼玩家認為輕鬆上手、適合多人同樂的休閒作品；另一方面，核心賽車玩家則批評其難以精準操控、關卡重複性高且缺乏深度。整體來說，這是具實驗性質的體感賽車遊戲，在Wii剛起步的年代提供「非寫實、重娛樂」的賽車選擇。

Monster 4x4: World Circuit (Japanese title: モンスター4×4 ワールドサーキット) is a racing game developed and published by Ubisoft in 2006. It was one of the early third-party titles released for the Nintendo Wii. The game’s primary selling point was its emphasis on motion controls, aiming to blend exaggerated off-road racing with party-style game design, particularly targeting families and casual players.

The game revolves around a world tour of race tracks, where players drive massive monster trucks—customized four-wheel vehicles with extremely high suspension and powerful engines—across various extreme terrains around the globe. Although it lacks a clear narrative or character-driven story, the arrangement of races and the game’s visual style evoke a sense of adventurous world travel and conquering nature’s harshest environments. From the Sahara Desert to frozen polar landscapes, from ancient ruins to urban circuits, each track is presented with bright, cartoonish visuals that create a lively and whimsical racing atmosphere.

In terms of gameplay, Monster 4x4: World Circuit fully utilizes the motion-sensing capabilities of the Wii Remote. Players hold the controller sideways like a steering wheel, tilting it to steer, and using buttons to accelerate, brake, or jump. The tracks feature numerous jump ramps, stunt loops, and obstacles that encourage players to perform over-the-top maneuvers to earn turbo boosts or score bonuses. Some courses even include vertical jumps and loop-the-loops, adding to the game’s dynamic pace and arcade-like feel.

The game also includes an item-based attack system, similar to that seen in the Mario Kart series. Players can collect power-ups on the track to attack opponents or defend themselves, using items like rockets, oil slicks, or turbo boosts, which adds an element of unpredictability and excitement to the races. Additionally, the game supports local multiplayer for up to four players in split-screen mode, along with time trials and stunt challenges to increase replay value.

However, the game received mixed-to-negative reviews upon release, especially among professional critics. While some praised the creative premise and the attempt to innovate with motion controls, many found the overall execution lacking. The visuals were considered overly simplistic, and when compared to contemporary Wii racing games like Excite Truck, Monster 4x4 came across as technically inferior. The physics engine was criticized for its lack of realism, and controls were often described as floaty or unresponsive, making high-speed navigation or stunts frustrating for more experienced players.

Player reactions were divided. On one hand, families and younger gamers found it easy to pick up and fun for casual multiplayer sessions. On the other hand, racing enthusiasts criticized its imprecise controls, repetitive tracks, and lack of depth. Overall, Monster 4x4: World Circuit is best seen as an experimental motion-controlled racing game that offered a lighthearted, non-simulation experience during the Wii’s early lifecycle, catering more to party gameplay than competitive racing fans.
