you only have the first 3 party members during the first world, then you those 3 knidnapped and replace them with 3 new ones (except for MC), then the same pattern repeats on the 3th world, you also unlock new classes like tank, flower, demon, cat and scientist.
from the 4th world and foward you get everyone back for a total of 10 characters and clear another 8 worlds (total of 12 worlds) miitopia is an actually pretty lenghty RPG, the only chuubas who actually cleared it are nui and rena and they kept a very decent viewership during doing so cause jrpgs are their forte.
