I won’t leave you guessing. I’ll state the names right off the bat: Daisy, Wario, Waluigi, and most recently, Nabbit.
Only one of these characters has starred in their own games so far. Their reception has ranged from relatively warm to ice cold. Their appearances are varied in frequency. It’s reasonable to say that none of them have truly come of their own yet. So what should Nintendo do with some of its less prominent characters?
