What was the first Nintendo-published game released on a Game-Key Card?

Pokémon Pokopia was the first game published by Nintendo to be released on a Game-Key Card.

A Game-Key Card is a physical game card that provides a key for downloading the software rather than containing the complete game data on the card itself. Pokopia’s physical edition used this format for its Nintendo Switch 2 release.

The distinction is important because Pokopia was not merely the first Pokémon title associated with the format; it was identified as the first Nintendo-published game released on a Game-Key Card. This makes its physical distribution part of the game’s technical history.

Pokopia was also the first Pokémon game released exclusively for Nintendo Switch 2. Those two facts are related to its 2026 launch but describe different milestones: one concerns the console platform, while the other concerns the physical software format.
