Not played it myself but from what I have seen on the Internet most of Dr Kawashima's Brain Training Switch can only be played with the touch screen.. Of the 24 different puzzles 21 are touch screen only aparentlyThat's... actually not a bad idea. Afaik there's no touch screen only games on switch, and every game requiring touch screen input in handheld mode can be controlled with controllers in docked mode. At least there won't be compatibility issues like the pstv had. If nintendo could upgrade the tegra soc to some recent models based on ampere architecture that could do 4k, I might as well pick one up.
Still pretty much all games can be played without using touch screen unlike psvita, in fact some people use the swith always in the dock like a home console.Not played it myself but from what I have seen on the Internet most of Dr Kawashima's Brain Training Switch can only be played with the touch screen..
