任天堂自家推出的遊戲沒有出現在PC或Steam平台，主要原因在於其整體經營策略與品牌定位。

首先，任天堂自認是以硬體與軟體結合為核心的娛樂公司。自從紅白機（Famicom）時代以來，就堅持將遊戲內容與自家主機平台綁定，透過軟體獨佔來帶動硬體銷售，這也是所謂的「賣主機靠遊戲」模式。像是《薩爾達傳說》、《超級瑪利歐》、《動物森友會》等高人氣作品，皆是推動Switch銷量的關鍵，如果這些作品也能在PC上玩，那麼人們購買任天堂主機的誘因就會大大降低。這與Sony或Microsoft的策略不同——這兩家公司雖然也有主機，但特別是Microsoft已逐步將Xbox遊戲推向PC，因為其核心業務包含作業系統與雲端平台，本身就與PC市場密切連結。

其次，任天堂重視封閉式平台的品質與控制權。他們希望能在自家的生態系統中全權掌控遊戲體驗，包括操作介面、性能表現、更新節奏與使用者行為。PC平台的自由度雖高，但也伴隨著各種不確定性，例如硬體規格參差不齊、作弊與盜版風險、以及模組或非官方改版干涉原始遊戲設計。對任天堂這種講求家庭友善、品牌一致性與可預期體驗的公司來說，開放平台反而會削弱他們對產品的控制力。

再者，任天堂本身並沒有PC軟體銷售與發行的歷史與基礎，也缺乏如Steam那樣的數位發行管道。他們的Nintendo eShop是個封閉系統，不與其他平台共享用戶資料、成就系統或雲端存檔等功能。在這樣的結構下，將遊戲移植到PC意味著要投入額外資源做適配、測試與客服支援，而任天堂顯然不認為這能帶來與主機獨佔同等甚至更高的商業利益。

總體來說，任天堂選擇不將自家遊戲上架PC或Steam，是因為他們以維持主機生態圈的競爭力為優先，並且重視封閉平台的內容控制與體驗品質。這種策略雖可能限制遊戲的觸及範圍，但卻成功建立以主機為核心、遊戲驅動硬體的獨特商業模式，也讓任天堂在主機市場中保持長期穩定的優勢。

Nintendo's first-party games have not appeared on PC or Steam mainly due to the company's overall business strategy and brand positioning.

First and foremost, Nintendo considers itself an entertainment company that centers on the integration of hardware and software. Since the days of the Famicom (NES), the company has firmly adhered to the principle of tying game content to its own hardware platforms. Through exclusive software titles, Nintendo drives the sales of its consoles—an approach commonly referred to as the "selling hardware through software" model. Popular titles like The Legend of Zelda, Super Mario, and Animal Crossing are key drivers of Nintendo Switch sales. If these games were available on PC, the incentive for consumers to purchase a Nintendo console would be significantly reduced. This strategy contrasts with that of Sony or Microsoft. While both companies also produce consoles, Microsoft in particular has been steadily moving its Xbox titles onto PC, as its core businesses—such as operating systems and cloud platforms—are closely tied to the PC market.

Secondly, Nintendo places great value on the quality and control of its closed platforms. The company seeks to maintain full oversight of the user experience within its own ecosystem, including interface design, performance standards, update schedules, and player behavior. Although the PC platform offers greater freedom, it also brings a range of uncertainties, such as inconsistent hardware configurations, risks of cheating and piracy, and the presence of mods or unofficial versions that can alter the intended design. For a company like Nintendo, which prioritizes family-friendliness, brand consistency, and a predictable experience, such openness could compromise their control over the product.

Furthermore, Nintendo lacks a history and infrastructure for PC game sales and distribution. It does not operate a digital storefront comparable to Steam. The Nintendo eShop is a closed system that does not share user data, achievements, or cloud saves with other platforms. Porting games to PC would require additional resources for optimization, testing, and customer support—an investment Nintendo may not see as yielding commercial returns equal to those of exclusive releases on its own consoles.

In conclusion, Nintendo's decision not to release its first-party titles on PC or Steam stems from a deliberate strategy to preserve the competitiveness of its console ecosystem and ensure tight control over content and quality. While this approach may limit the reach of its games, it has successfully established a unique business model centered around proprietary hardware powered by exclusive software—a model that continues to secure Nintendo’s long-term strength in the console market.
