The selection of bonuses a Mii can get upon level-up differs:.Players cannot freely edit song lyrics with the keyboard, only being able to use pre-made words and phrases instead.
Singing Miis also cannot be put into groups.Songs are performed directly inside the Mii's apartment, rather than inside the Concert Hall.In Tomodachi Collection: New Life, they turn their head towards the thrown item almost immediately. If the item intended to be given to a Mii is launched high in the room and falls behind them, it becomes horrified in shock for a few seconds before turning his/her head back towards the tossed item and walking over to pick it up.The animations Miis make when they eat their favorite/worst favorite are different.Miis only have one all-time favorite dish and one worst dish instead of two, lacking the "Super" favorites.
Depending on how much they like it, the Mii's happiness will go up, and once it reaches a certain point, the Mii will level up, allowing the player to give them a level-up gift, such as a phrase or a song as a reward. Miis themselves can also be interacted with in their apartment, allowing the player to give them food, clothes, or an interior for their apartment. 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.
