Did the steam link really go nowhere? I have a physical box, and it works magically well. My understanding is it's still available, just not as a physical box.
Do any major Switch emulators natively support JoyCons the way Dolphin does WiiMotes? (Do JoyCons even use regular ol' Bluetooth the way the WiiMotes do? EDIT: quick Google says yes :) )
It currently sits in a box somewhere in my house because I have never had any use for it, which I think is the case for most PC gamers, hence its failure.
