Pokémon Pokopia

Players control a Ditto who is imitating a human. The player can customize the Ditto's appearance, including skin color and hair color, as well as clothing. The game features crafting and building mechanics that players use to befriend new Pokémon, who can then teach the Ditto new moves to use to interact with the environment. These abilities allow Ditto to perform various tasks; these include creating bushes, watering dry plants, cutting debris, and smashing rocks.

As players progress and build the area around them, they attract more Pokémon. These Pokémon can assist Ditto in cultivating the world around them and converse with other Pokémon. Each Pokémon can be found in different habitats that Ditto needs to create in order for them to appear, such as planting grass under a tree or putting a punching bag next to a bench. They also have their own needs, such as the Pokémon Hoothoot, who enjoys darkness.

The game takes place in a post-apocalyptic version of the Kanto region.

A Ditto finds itself in a world abandoned by humans and uninhabitable to Pokémon. After finding its trainer's old Pokédex and assuming a form based on them, it meets a Tangrowth, going by "Professor Tangrowth", who has tasked himself with studying the environment and solving the mystery as to why humans and Pokémon have left. After finding a Squirtle and helping it recover from dehydration, Ditto is tasked with restoring various habitats so the Pokémon population can recover. Along the way, Ditto and Professor Tangrowth find a mysterious tower that initiates a "Team Initiation Challenge", where Ditto must provide certain items for the supposed wellbeing of Pokémon.

Pokémon Pokopia was initially conceived by Pokémon Scarlet and Violet director Shigeru Ohmori during that game's development as a spinoff. When thinking about potential new approaches for the franchise, Ohmori began to dwell on his earliest work in the series as a map designer on Pokémon Ruby and Sapphire, and thought it would be appealing for fans to be able to create their own Pokémon habitats. As Game Freak lacked experience in the sandbox game genre, Koei Tecmo's Omega Force was chosen to co-develop the title alongside them on recommendation from The Pokémon Company, as Omega Force had previously worked on similar titles such as Dragon Quest Builders 2. Ohmori served as the concept and senior director of the game, while Omega Force director Takuto Edagawa served as chief director.

Koei Tecmo's Marina Ayano served as the game's art director. Pokémon Pokopia was produced by Kanako Murata.

According to the review aggregator website Metacritic, Pokémon Pokopia received "generally favorable" reviews. It is the highest-rated Pokémon game on the site. Fellow review aggregator OpenCritic found that 98% of critics recommended it. In Japan, four critics from Famitsu gave the game a total score of 39 out of 40, with three reviewers giving the game a perfect score of 10.

Eurogamer writer Lottie Lynn found Pokémon Pokopia similarly strange to other Pokémon spinoffs due in part to its humanoid Ditto, while considering the combination of elements from Animal Crossing and Minecraft sensible. She was particularly happy with the implementation of the game's real-time 24-hour clock, stating that, because it was put in the menu rather than on-screen during normal gameplay, it helped her focus on what she should be doing rather than when she should be doing it, as well as introduce strategic elements to cultivation. She also stated that the game starts out somewhat slow, but becomes more exciting as the game becomes more complex.
