Is the reason PS5 and and Xbox are so low compared to Nintendo because Sony and Microsoft are american companies now ?
Or is it the fact most people are leaning towards a switch/steam deck/portable and a pc globally these days ? My son has NO interest in consoles, he plays pc games with his friends or mobile games on his phone.
Microsoft, on the other hand, has been actively seeking those games and making them available via Game Pass and their cloud streaming platform, which what may be driving those unit sales.
from Famitsu[1], all top 10 best-selling games are Switch games.
It the console don't have attractive games, Player won't buy it.But if the console doesn't sell well, game studios will hesitate to make exclusive game for it.
So yes, Currently only Switch has more "Japanese game" now.
