It's a life sim where you can add Miis to an island and watch them develop relationships and a lot of other stuff. You can help them solve problems to get money, which you can use to buy clothes, food, interiors to their rooms, and more. I recommend watching videos on it.

If you can get it for a price that isn't expensive, I would get it. It's kind of like the Sims.

Also, things happen while the game is closed, so you should check on your Miis once in a while.

While Elijah's explanation is very good, I feel it leaves something important out... Just how funny random things can get. (I just saw the pringles guy ask an orca about her battle-ax proficiency...) Additonally, free is a very good price, and the modding community is still good

Turns out I really liked it, though I'm not a big fan of making a thousand Mii from scratch, but I see potential on this game. Thanks a lot, guys! :)
