This makes sense given that the Miis are supposed to be driven by relationships, but it can lead to watching battles play out more than actually participating in them. The only major problem with the turn-based system is that only one Mii is playable. Miis that spend time together generally become better friends (or romantic partners?). Relationships are developed between battles in surreal Tomodachi Life-esque cutscenes. Unique to Miitopia is a relationship system that allows Miis to team up for attacks during battles (or hinder each other out of spite).
Unlike the Paper Mario series, Miitopia thankfully sticks to the tried-and-true RPG formula: battling monsters, leveling up, and unlocking new skills in the process. The main gameplay consists of turn-based battles using party of customizable Miis. I recommend trying to demo before paying full price for the game. I was pretty much sold on the game after playing through the demo and messing around with the new Mii Maker tools. I'll start out by saying that I skipped over Miitopia on the 3DS in 2017, so this game was a fresh experience for me.
