The quality requirements of the Nintendo's storefront are ridiculously low. I've seen footage of the Switch WWE game and frankly it should never have been allowed into any store front, let alone the one people expect to be better.
There are plenty of platformers out there, but only one company can use Mario. The games on the Switch are pricey, but the console is affordable, making it excellent for multiplayer gaming.
I don't think it has a lower price and better games in practice. They did manage to corner the portable gaming space with their 3DS and Switch, which all major competitors abandoned. Now they're at risk of losing that too.
