As more Miis are added, more facilities and activities are unlocked, and the Miis may even become friends with one another, hanging out in their apartment or outside. Once each Mii is made, they will move into their own apartment on the island, allowing them to explore the island and its various facilities.
These Miis can be given a personal voice and personality based on the player's liking. The game takes place on an island in the middle of the sea, that can be populated with various Miis created from the built in Mii Maker, or transferred wirelessly from a Wii console.
