The Makeup Menu, which allows you to further customize you Miis. The Outings, which allows you to send you Miis out on outings increasing there relationship levels. The switch version also gives you a horse companion which give you added abilities based on your relationship. Miitopia is simple, but highly recommend due to its massive levels of charm.
