I want to have a set theme throughout my islanders, but I can't think of anything. Personality distribution doesn't matter to me, and gender distribution only matters enough to unlock everything.
Hard to think of a theme that you can make 100 Miis for. My Miis were all pretty random... plus my brother and I share the game, so we both picked out Miis.
I been playing Tomodachi Life for almost a year i don't have a specific theme, but i reset the game and made themed as "one of my projects" themed. What project? Can't tell. But depends of the theme you want.
