The one holdout among the console makers is Nintendo, whose PC strategy is still to threaten fan projects with lawsuits. Perhaps I do not have to hand it to Nintendo for this, but as a result of its obstinance, the Switch is the only console I'd consider buying as a PC gamer. Nintendo remains a one-of-a-kind gaming company, whereas Xbox and PlayStation feel less and less distinguishable from gaming at large—aka PC gaming.
I'm not sure about this analysis of the Switch's success. The "lawsuit" argument is pretty irrelevant; the console would sell regardless of whether emulation existed (as it has, for most of the big titles and for much of the console's life). I think the "one-of-a-kind" argument is accurate, but I'd also suggest that the very wide library of games is a major reason why Nintendo has performed so well in this generation. The Switch appeals to almost every single type of gamer - there is so much variety there. Additionally, the portability is clear point of difference: for many, the Switch is more like a handheld that they can occasionally play on the TV, rather than a traditional home console. And finally, the Switch is just a more affordable option and that has mattered a lot since 2020.
