D4 Enterprise is actively expanding its EGG Console retro game service on Nintendo Switch and Steam, adding multiple classic Japanese PC titles through late 2026, while its Platz division releases die-cast construction models.
D4 Enterprise has spent 2026 broadening the reach of its EGG Console line, which re-releases classic Japanese PC games on modern platforms. The company has moved beyond its home base on the Switch, bringing titles to Steam, and has kept a steady cadence of releases that preserve original quirks while adding modern conveniences. Recent additions include a 1986 MSX2 action adventure, a 1994 PC-9801 real-time strategy, and a rebalanced version of a foundational Falcom action RPG.
The service has also become a destination for early adventure and action games from the 1980s. In September, D4 Enterprise made the 1983 text adventure Seinaru Ken free to Project EGG subscribers, a title developed with the creator of Mugen no Shinzou on the team. That same month, the MSX action RPG Volfes and the 5 Demons joined the lineup as the 114th EGG Console title, and the PC-9801 version of Puyo Puyo landed as the 113th. Each release follows a similar template: the original game, a modern platform, a price point around 880 to 980 yen, and often a Gallery mode for viewing manuals and packaging.
Preservation is a consistent thread. The EGG Console reprint of Puyo Puyo keeps PC-9801-specific display traits, and Relics MSX2, released on both Switch and Steam, includes a Scene Select mode and a Gallery. The company is also handling physical products through its Platz division, which will release three die-cast Komatsu construction models in September. The retro game push remains the core of its activity, with titles arriving at a pace that keeps the EGG Console catalog growing through the summer and into the fall.
