PC games are built with power in mind that Switch does not have. So you couldn't play them. Switch games are not built with m+kb support, so that would be pointless.

The comment you were replying to directly answers you question about the point:
> PC games are built with power in mind that Switch does not have
The part of comment about "can be played without K+M" is entirely irrelevant to what I am saying because the preference _for_ K+M is the premise of this whole comment subtree.
