I'll be a little autistic here
Nintendo has done more than nostalgia, one of the best selling games to come out for the switch was splatoon 2 a franchise that started on the Wi-U. They tried with arms and occasionally try to put out a new IP that don't sell. You are also forgetting the third party companies that are exclusively nintendo which brings franchises like pokemon, bayoneta, Fire emblem and kirby onto their system. They've actually done a great job of supporting companies and giving funding for exclusivity. From Demon X Machina to Untitled goose simulator they are helping in the production of niche titles from game genres considered dead to consoles. Theres also smash bros which I'm kind of surprised nobody mentioned. By no means does nintendo beat P.C. but they definitely have a better selection then the X box or the play-station.
I mean yeah I'm being a fagot about this since nintendo is getting lazier with each new game in a franchise. see pokemon, I mean hell we don't even have a new mariokart for the switch. They have shelved franchises like metroid out of fear of failure or inability to understand what made that game good. They've also refrained from lootboxes or microtransactions from their main games so you know that's always a solid plus. You can still hate them for picking weaker consoles and relying on gimicks to sell their systems but you can't in good faith say they have nothing to offer past mario and zelda.
All that being said there's not a chance in hell that Blobos love of nintendo is due to anything other then an autistic atachment to a brand in desperate need of a kick to the groin. He likes that it's popular and loves the fact that he picked the side in the console wars that won. He loves the fact that Nintendo is loved by the woke P.C. crowd and that certain games are bending to the will of western audiences, see fire emblemb three houses. He's also sunk too much emotional energy into it to let nintendo be anything other than perfect. Think about it if Nintendo isn't the mesiah of game companies then he's the dick for skiping out on a funeral to play mario.
