Game Freak developed Pokémon Red and Green, the original games commemorated by Pokémon’s 30th anniversary.
Game Freak was founded by Satoshi Tajiri and Ken Sugimori after their earlier video-game magazine project. The studio created the role-playing game and designed its systems, world, characters, and creatures. Nintendo published the games for the Game Boy.
Nintendo, Game Freak, and Creatures later became the three principal companies associated with Pokémon’s ownership and management. This sometimes causes people to answer Nintendo when asked who developed the original games. Nintendo was the publisher and platform company, while Game Freak was the developer.
Creatures also became deeply involved in Pokémon, including character modeling and other game projects. The franchise’s large-scale production therefore rests on several companies, but the specific developer credit for the first main games belongs to Game Freak.
