《胡言山的魔理沙》是充滿濃厚二次元風格與桌上遊戲要素的角色扮演遊戲（RPG），由UnknowX開發，Alliance Arts Inc.發行，並獲得《東方Project》官方授權，屬於其正規認可的二次創作作品。於2025年9月19日發售，登上Steam、Nintendo Switch以及Nintendo Switch 2雙平台，並特別支援繁體中文語言版本，同時推出實體卡帶版本，對收藏家與東方粉絲來說別具價值。

設定於一座神秘莫測、充滿謊言與奇幻氣息的「胡言山」——也被稱為「書之山」，這裡是個知識、文字與幻想共存的迷宮世界。故事從靈夢接獲異變報告開始，得知長年夥伴霧雨魔理沙在山中失蹤，音訊全無。作為博麗巫女的她毅然踏上旅程，深入書之山尋找魔理沙的下落。旅途中，她將遭遇各式各樣的角色、陷阱與謎題，而每一次行動的選擇，都將由玩家與骰子的投擲結果共同決定，強烈呼應桌上型角色扮演遊戲（TRPG）的核心魅力。

玩法融合視覺小說與TRPG要素，操作靈夢，透過回合制的選擇與擲骰系統推進劇情。每個場景都設有「行動選擇」，並根據不同的角色能力值與骰子結果產生變化。例如，若選擇進行「說服」、「搜索」、「戰鬥」等行動，就必須依賴靈夢的對應數值與運氣來判定成敗。這樣的機制讓每一場遭遇都充滿不可預測性，也使得故事體驗呈現豐富的變化與重玩性。

在畫風上延續東方Project一貫的日式幻想風格，但加入更多柔和的插畫筆觸與新角色設計，使整體視覺呈現更具童話與奇幻書籍的氛圍。角色之間的互動對白精緻有趣，不乏東方系列特有的輕鬆幽默與角色個性碰撞。還收錄大量支線任務與隱藏內容，透過探索與角色關係推進，解鎖多種不同的結局，並深入了解「謊言之山」背後所藏的真相與魔理沙的命運。

在操作方面，對應手持與電視模式，介面設計清晰，並針對新玩家加入詳細的骰子機制教學與提示系統，使不熟悉TRPG風格的玩家也能輕鬆上手。Switch 2版本針對新機硬體進行畫面優化與快速載入支援，體驗更加流暢。

上市前的試玩與展示會引起粉絲社群廣泛關注與期待，特別是東方圈的玩家紛紛讚賞其對原作角色的尊重與細膩刻劃，同時也對這種「TRPG式劇情互動」結合東方世界觀的創新嘗試表達肯定。有評論指出，遊戲或許不以戰鬥為核心賣點，但卻憑藉著獨特的玩法與充滿想像力的劇情設計，在日式獨立RPG作品中嶄露頭角。

整體而言，《胡言山的魔理沙》是別開生面的敘事冒險RPG，它結合傳統桌遊元素與東方Project世界觀，以全新的方式呈現角色關係與故事發展。無論是《東方Project》的忠實粉絲，或是喜愛劇情導向、角色選擇與骰子機制的玩家，都能在這部作品中找到趣味與感動。這不僅是一場尋人的旅程，更是對於「信任與真相」的內心探問。

“Marisa of Liartop Mount” is a role-playing game (RPG) rich in anime aesthetics and tabletop game elements, developed by UnknowX, published by Alliance Arts Inc., and officially licensed by the Touhou Project as a recognized derivative work. The game is set for release on September 19, 2025, and will be available on Steam, Nintendo Switch, and Nintendo Switch 2, with full Traditional Chinese language support. A physical cartridge edition will also be released, making it a valuable collector’s item for Touhou fans.

The story unfolds on a mysterious and fantastical mountain called Mount Huyanshan — also known as the “Mountain of Lies” or the “Mountain of Books.” This world is a labyrinth where knowledge, language, and fantasy intertwine. The story begins when Reimu, the Hakurei Shrine Maiden, receives a report of a new anomaly and learns that her longtime friend Marisa Kirisame has gone missing somewhere within the mountain. Determined to find her, Reimu embarks on a journey into this enigmatic world. Along the way, she will encounter a wide cast of characters, face traps and puzzles, and make crucial choices — all of which are governed by both player decisions and dice rolls, echoing the spirit of traditional tabletop RPGs (TRPGs).

The gameplay blends visual novel storytelling with TRPG mechanics. Players control Reimu through a turn-based choice-and-dice-roll system that drives the story forward. Each scene presents “action options” such as persuading, searching, or fighting. The outcome of these actions depends on Reimu’s stats and the roll of a die, adding unpredictability and depth to each encounter. This system encourages replayability and a dynamic narrative experience, where every choice can lead to new outcomes.

Artistically, the game maintains the signature fantasy aesthetic of the Touhou Project, while introducing a softer illustration style and new character designs. The visual presentation evokes the feeling of a whimsical storybook. Dialogue between characters is sharp, charming, and infused with the lighthearted humor and personality clashes that fans of the series will recognize. The game also features numerous side quests and hidden content, allowing players to uncover multiple endings and gradually reveal the truth behind the Mountain of Lies and Marisa’s mysterious fate.

From a technical standpoint, the game supports both handheld and docked play modes, with a clean, user-friendly interface. For newcomers to the TRPG genre, it includes an in-depth tutorial and helpful prompts to ease players into the dice mechanics. The Nintendo Switch 2 version is optimized for improved performance, offering enhanced visuals and fast loading times.

Pre-release demos and showcases have garnered significant attention and anticipation within the fan community — particularly among Touhou enthusiasts, who have praised the game’s faithful characterization and thoughtful narrative. The innovative combination of TRPG-style interaction with the Touhou universe has also been positively received. Some reviewers note that while the game does not focus heavily on combat, its unique mechanics and imaginative storytelling help it stand out among Japanese indie RPGs.

In conclusion, “Marisa of Liartop Mount” is a refreshing narrative-driven RPG that creatively combines tabletop role-playing elements with the beloved Touhou Project world. It presents character development and storytelling in an entirely new format. Whether you’re a devoted Touhou fan or a player who enjoys story-focused gameplay, character-driven choices, and dice-based mechanics, this title offers a compelling and emotional journey. More than just a search for a missing friend, it’s a heartfelt exploration of trust, deception, and truth.
