There's also a more obvious answer here. Nintendo's sequel's of their core franchises always sell about half as much as the first title. Even when the quality is unquestionably much better:
DKC sold 9.3 million, but the unquestionably superior DKC2 sold only 5.2 million
Mario Galaxy sold 10 million, but the unquestionably superior Mario Galaxy 2 sold only 6.7 million
This sort of trend goes on regardless.
Ocarina of Time sold 7.6 million, Majora's Mask sold 3.8 million.
This is just how things go.
I describe myself as a little dose of toxic masculinity.
