In most of not all cases, traditional gaming consoles are sold at a loss. A cursory search says that’s true for the switch 2 as well, but I have not investigated with any effort.

It really seems like it would behoove everyone to sell their games on PC, whether that’s their own client or an existing one like Steam. Nintendo will never get a dollar from me because I will never buy their hardware. I would however at least consider buying some of their titles if they were available on Steam. I’m definitely not alone.
