D4 Enterprise Co., Ltd. (株式会社D4エンタープライズ, Kabushiki-gaisha D4 Entāpuraizu) is a Japanese video game publisher currently specializing in content delivery services like Project EGG over the Internet.
D4 Enterprise has operated as a Japanese publisher since 1983, though their modern output on PlayPile shows a company that has shifted focus significantly over time. The data indicates they have released 17 titles in total, with 16 appearing under their publishing credit and only one where they are listed as the developer. Their catalog spans nearly four decades, but the volume of releases has changed drastically. They were most active in the 1990s with seven games, followed by three in the 2000s. Activity slowed to two games each in the 1980s and 2010s, with just one release in the 2020s so far. Their genre portfolio is heavily anchored in arcade-style action. Seven of their games fall into the Arcade category, while Adventure titles make up five entries. They also have a strong presence in Fighting games with four releases and Puzzle games with three. Their platform reach covers nine different systems, with PC (Microsoft Windows) being the most common at nine titles. The Wii follows closely with eight games, and legacy hardware like the Neo Geo AES and CD versions appear seven and six times respectively. Quality varies across their library, but the average rating sits at 73.1 out of 100 based on eight rated titles. The breakdown shows a generally positive trend with four great scores above 80 and three good scores between 60 and 79. There is only one mixed-rated title, and no poor ratings appear in the data. Their highest-rated recent work is Mado Monogatari: Fia and the Wondrous Academy from November 2024, which holds an 82 score. Older classics like Metal Slug 3 (2000) and The King of Fighters '97 (1997) also maintain high scores around 81. Despite this history of action games, the company bio notes a current specialization in content delivery services rather than just game publishing. Their website lists Project EGG as one of their internet services. While they still release titles like Nyoki Nyoki: Tabidachi-hen and Dragon Slayer Chronicle, their recent output is sparse compared to their earlier years. Players looking for a specific genre will find a solid selection of Fighting and Arcade games, but the company is no longer producing at the same rate as in the 1990s.
