Tomodachi Collection

Tomodachi Collection is a 2009 social simulation video game developed and published by Nintendo for the Nintendo DS solely in Japan. The game follows the daily interactions between user-created Miis who reside on an island overseen by the player.

The game was initially formulated by junior Nintendo employees in October 2005 as an imitation of the Nintendo-published fortune-telling video game Tottoko Hamtaro: Tomodachi Daisakusen Dechu. Originally titled Otona no Onna no Uranai Techō, the game's character creation system served as the progenitor for what would formally become the Miis. The team was reassigned to implement the Miis onto the Wii console, during which the game's production was put on hold. Following the Wii's release in December 2006, the project restarted as Tomodachi Collection. Developers sought to create a distinctive and engaging gameplay experience that emphasized the human-like characteristics of the Miis, whom players were incentivized to create in the image of their real-world friends and family.

Tomodachi Collection released in Japan on June 18, 2009. It was a critical and commercial success, garnering favorable reviews and selling 3.2 million copies by March 31, 2010. Following unrealized plans to localize the title overseas, Tomodachi Collection was followed up by the internationally-released sequel Tomodachi Life for the Nintendo 3DS in 2013. Another sequel, Tomodachi Life: Living the Dream, is scheduled for release on the Nintendo Switch on April 16th, 2026.
