As we know, Yo-Kai Watch is already extremely popular with kids so if we had Sun & Moon aimed at older players (and is only recommended for older players due to a mature rating classification) it'll be bad for Pokemon who are trying so desperately to win back fans who switched to Team Yo-Kai.
That's true, totally forgot about Yo-Kai to be honest.
But I heard somewhere that Yo-Kai didn't work much in western countries, and that Pokemon is still more popular?
