My development PC running linux (I don’t use Arch, BTW) + Steam has by far the most games I’m interested in playing. Games that I have played my entire life run great, through DOSBox, Proton, native, or console emulators.
That being said, I still have a huge soft spot from my old 3DS and wish I still had it. Sure the Switch is great, but the 3DS had so many fun little quirky features that it was just fun to use as well as play games on.
