The wiimotes are just bluetooth and the tracking is 5 LEDs. I've used candles instead of the sensor bar before. You can buy a "dolphin bar" for $20 and use your wiimotes on the PC. It works great. I dumped my wii games and haven't touched the console in years.

Yeah I've used the candle trick with a Wii before too, but that doesn't mean it isn't a much larger barrier for entry than Switch games working most of the time with just a standard controller (and therefore keyboard mapping). As for controllers, I don't think I even had bluetooth in a desktop PC until somewhat recently (~3 years ago) when I paid a little extra for a motherboard with WiFi 6 and BT built-in.

The $20 dolphin bar also is a bluetooth adapter.
