I have a (now retired) relative who spent a majority of his career as a high-level MSFT exec, and he knew a lot of the OG Xbox guys. As a kid in the early 2000s who grew up with Nintendo consoles, I asked him over the years more than once why there was no effort to purchase Nintendo.
His answer every time was a simple "the Japanese corporate culture and the American corporate culture have differences in ways that money simply cannot overcome"
As much as I'd love to be able to play Mario or Zelda in 4k 60fps, or play FZero or Smash Brothers over Xbox Live, it's just not gonna happen.
