[1] Miitopia supports the ability to import Miis and their trait settings from Tomodachi Life, as well as from players' friend lists.

[1] The Nintendo Switch remaster introduces a new makeup and wig feature which allows players to further customize their in-game characters, including options not available on the console's Mii Maker application.

Soon, the Dark Lord, who can steal faces from Miis and use them to control peaceful creatures and turn them into monsters, attacks the town.

Along the way, the player creates more companions, meets the Great Sage, and reaches Greenhorne's castle, where the quest continues after the Dark Lord steals the faces of the King and the Princess.

The hero is tasked with saving the three Fab Fairies of the Realm, who show the team the way to the Dark Lord's castle in Karkaton.

After retrieving their faces, the Fab Fairies open the door to Karkaton; when the team arrives there, the Dark Lord attacks again, stealing the hero's new companions but not their powers.

[5] Many critics have drawn comparisons between Miitopia and Tomodachi Life[6][8][7][12] due to the two involving Miis and having similar mechanics, despite having different premises.

[7] Similarly, Heidi Kemps of GameSpot felt that Miitopia was a "slow slog you mostly watch rather than play",[8] and Jon Mundy of Pocket Gamer also discussed the lack of challenge and player input.

[8][12] Despite this, Frank praised the creative "hidden intricacies" of the battle system, due to characters' jobs and personality traits affecting their combat style.

[16] During its first week in the UK, the Switch port sold 36% more copies at launch than the 3DS version, debuting at #2 behind Resident Evil Village.

[17] In Japan, the Switch port launched at #2 behind Rune Factory 5 with 72,725 physical copies sold, three times the sales of the 3DS version.
