The game is called Tomodachi Life, or "Friend Gathering Apartment". The game begins with the player naming their island and creating or importing their personal Mii, which is the player's "look-alike", who lives in a tiny apartment building. The building can grow, allowing the player to have 100 Miis on the island. Heather's daughter wanted her to play it with her...and it turned out to be super-addictive!!
