《紙片瑪利歐：摺紙國王》（Paper Mario: The Origami King）是任天堂於2020年在Switch平台推出的紙片瑪利歐系列第六部作品。延續系列一貫的幽默風格與紙藝美術風格，結合冒險探索、解謎與回合制戰鬥，並導入全新的「摺紙」主題，在劇情與遊戲機制上都帶來明顯的革新。

故事劇情圍繞在由摺紙王國入侵蘑菇王國的災難。主角瑪利歐受邀前往碧姬公主的城堡參加慶典，卻發現城堡遭到神秘的摺紙化，連碧姬本人也被摺成怪異的樣子。這場事件的幕後黑手是新登場的反派「奧利王」（King Olly），他自稱為摺紙之王，企圖以摺紙魔法重塑整個世界，把所有紙片生物摺成他的子民。

為了阻止奧利王的陰謀，瑪利歐與新夥伴「奧莉維亞」（Olivia，也就是奧利王的妹妹）聯手，展開一場解放城堡、對抗摺紙軍團的冒險。他們需要追蹤並解除綁住碧姬城堡的五條巨大絲帶，這些絲帶延伸至世界各地，分別連接著不同主題的區域，每個區域都藏有強力的守護者與關鍵的故事推進。

操作上，融合紙片系列傳統的RPG要素與全新的戰鬥系統。探索時將操作瑪利歐在充滿紙藝元素的世界中移動，解開機關、尋找隱藏通道、解救摺紙化的角色，並使用新的能力「千手之力」（1000-Fold Arms）來操控特殊場景中的巨型紙張，進行拉扯、摺疊等互動式解謎，這也讓紙張世界的概念徹底融入關卡設計。

戰鬥方面，導入獨特的「環狀轉盤式戰鬥系統」。每場戰鬥會進入一個類似轉盤的戰鬥盤面，敵人會散落在不同的位置，而首要任務就是在限制的回合數內透過轉動或滑動盤面，將敵人排列整齊，以利執行攻擊。排列整齊後，使用跳躍或錘子等招式造成成排傷害，是戰鬥中的關鍵技巧。雖然這種機制為傳統回合制注入新變化，但也有玩家認為後期戰鬥難度未明顯提升，解謎成分反而蓋過戰術思考。

此外，Boss戰也極具創意，與一般敵人不同，這些戰鬥需反轉站位，由Boss站中央、玩家圍繞外圈前進，藉由規劃移動路線、觸發道具與機關來逐步削弱Boss的防禦並進行攻擊。這些戰鬥不僅考驗玩家的判斷，也充分展現本作紙張主題下的創意與互動性。

關卡設計方面，《摺紙國王》擁有廣闊而多樣化的遊戲地圖。從森林、沙漠、雪山到忍者主題公園，場景風格變化多端，每一區都有獨立的故事線與特有的角色互動。遊戲世界中充滿各種「摺紙化的敵人」、可收集的「紙片托德」、隱藏寶藏與收集品，提供豐富的探索內容。大量幽默對話與奇特角色貫穿整個旅程，使得冒險過程輕鬆詼諧且充滿驚喜。

在市場評價方面，在推出後獲得整體正面的評價。評論普遍肯定其美術風格細膩、角色動畫流暢、遊戲世界豐富多彩，且劇情節奏掌握得當。尤其奧莉維亞作為原創角色，個性鮮明且討喜，成為玩家們非常喜愛的夥伴之一。雖然戰鬥系統的創新受到肯定，但重複性高、缺乏角色成長要素（如等級系統）也是一些玩家批評的點。

總體而言，這是視覺與創意表現俱佳的冒險RPG作品，融合紙片美術的幽默風格與豐富的解謎要素，提供充滿童趣、想像力與意外情感深度的冒險旅程。對於想體驗不同於傳統瑪利歐玩法的玩家而言，無疑是Switch平台上值得一試的代表作之一。

Paper Mario: The Origami King is the sixth installment in the Paper Mario series, released by Nintendo for the Switch in 2020. Continuing the franchise’s signature sense of humor and paper craft-inspired art style, the game blends exploration, puzzle-solving, and turn-based combat, while introducing a new origami theme that brings significant innovation to both its story and gameplay mechanics.

The plot centers around a disaster caused by the invasion of the Mushroom Kingdom by the Origami Kingdom. Mario is invited to Princess Peach’s castle for a festival, only to find that the castle has been mysteriously transformed into folded origami—and Peach herself has been oddly folded as well. The mastermind behind this crisis is a new antagonist named King Olly, who proclaims himself the Origami King. He seeks to reshape the world using origami magic, turning all paper-based beings into his obedient subjects.

To thwart Olly’s plan, Mario teams up with Olivia, King Olly’s kind-hearted sister, embarking on a grand adventure to free the castle and defeat the origami army. The goal is to trace and remove five massive colored streamers that bind Peach’s Castle. These streamers stretch across distant lands, each tied to a uniquely themed region, guarded by powerful bosses and advancing the narrative as players progress through them.

In terms of gameplay, the title combines traditional RPG elements from the Paper Mario series with a revamped battle system. During exploration, players control Mario as he moves through a vibrant world crafted from paper, solving environmental puzzles, uncovering hidden paths, and rescuing characters who have been folded into origami. A new mechanic called 1000-Fold Arms allows Mario to interact with special parts of the environment using exaggerated, extendable arms to peel, tear, or fold sections of the scenery, reinforcing the paper-themed setting in both visual and mechanical terms.

Combat introduces a fresh, unique system called the ring-based battle mechanic. Each battle takes place on a circular grid where enemies are scattered across different positions. Players must rotate or slide sections of the ring to line up enemies within a limited number of moves, allowing for more efficient and effective attacks. Once aligned, Mario uses jump attacks or hammer strikes to deal damage in rows or groups. While this puzzle-combat hybrid breathes new life into the series’ turn-based formula, some players noted that as the game progresses, the puzzles tend to overshadow tactical variety and the challenge doesn't scale dramatically.

Boss fights add even more creativity. Unlike regular battles, bosses are positioned in the center of the ring, and Mario must work his way inward from the outer edge. Players must carefully chart their movement path and activate tiles to damage the boss or trigger essential mechanisms. These encounters test player intuition and further highlight the game’s clever use of paper-based concepts.

The world of The Origami King is broad and diverse, with each region offering distinct aesthetics and storytelling. From lush forests and scorching deserts to snowy peaks and a ninja-themed amusement park, every area is brimming with life, personality, and unique characters. The world is populated with origami enemies, hidden collectibles, folded Toads to rescue, and cleverly placed secrets that reward exploration. Witty dialogue and quirky characters give the game its signature light-hearted tone, making the journey consistently engaging and full of surprise.

Upon release, Paper Mario: The Origami King received generally positive reviews from both critics and players. It was widely praised for its charming art direction, fluid character animation, vibrant world design, and well-paced narrative. Olivia, in particular, became a fan-favorite companion thanks to her expressive personality and emotional depth. While the innovative combat system was appreciated, some criticism was directed at its repetitive nature and the lack of traditional RPG progression elements, such as an experience and leveling system.

Overall, Paper Mario: The Origami King stands out as a visually stunning and creatively ambitious RPG adventure. By combining the humorous paper-craft aesthetic with thoughtful puzzles and heartfelt storytelling, it offers a whimsical yet emotionally resonant experience. For players seeking something refreshingly different from the usual Mario platformers, this title is undoubtedly one of the most memorable and worthwhile offerings on the Nintendo Switch.
