Miitopia is a pretty great video game. It has a complex but simple story and loads of customization. It's your story, you choose who the characters are and what they do. Miitopia has amazing music and sound effects and silly scenarios.

I found the rockfall event (the one where your party gets split into two) really tedious, especially during Karkaton and the Sky Scraper (more annoying in the latter, when the portion of the party you can't control has to fight a boss).
I couldn't see the Great Sage becoming possessed thing coming. Great plot twist, especially for the final boss. However, the Darkest Lord's one-hit-one-hp move is really annoying, especially if you're caught off-guard by it and it triggers One More Time.

I rate Miitopia a 9.5/10. It's easy for younger children (that can read) to play and it also provides some humor for older children, teens, and adults as well. I hope for there to be a sequel or remastering on the Switch in the near future. It's a shame that this masterpiece is underrated.
