Which two companies developed Pokémon Pokopia together?

Game Freak and Omega Force developed Pokémon Pokopia together.

Pokopia was co-developed by Game Freak and Omega Force. Game Freak is the Pokémon game studio associated with the franchise’s core video-game development, while Omega Force is a Koei Tecmo team known for large-scale action and other genre projects.

Their collaboration suited Pokopia’s design. Game Freak contributed Pokémon-world knowledge and character direction, while Omega Force brought experience relevant to creating an expansive, interactive environment. The resulting game combines familiar Pokémon creatures with construction, crafting, farming, and habitat management.

The publishing credits are different: Nintendo and The Pokémon Company published the game. Creatures is also a major Pokémon company, but it is not one of Pokopia’s two credited developers. Keeping development and publishing roles separate is the key to identifying the correct pair.
