Steam does have one huge thing over Nintendo. The PC platform is so backwards compatible that I can play games from the 80s on a brand new computer today.

Nintendo charges you money for new copies of each game you want to play on their latest hardware. You can't just pull out your old copy of Super Mario Bros and install it on your Switch.

Hell, I've heard that there are Switch games that have been out since the very beginning of the console that are still full price.
