The words "Nintendo Switch" and "graphical capabilities" are mutually exclusive, that much I agree with. However, it is a caveat that most people (I'd like to think) are very well in observance of. I, for one, pretty much made the decision to just buy titles on the Switch that I can't get elsewhere (granted, I made two exceptions because of nostalgia and portability-- Tactics Ogre Reborn and Crisis Core Reunion, because my PSP was stolen before I could get far in either game).
Barring those two titles, I purchase for the PC any game that I can play on Steam/Epic.
