I’ve been playing Switch games just fine on my SD. Currently enjoying Fire Emblem Engage which runs flawlessly, Three Houses also runs well. The same is true for many (most?) of the Switch library. I already have a 3DS but the Steam Deck can handle those games too. Likewise NDS games. I only play a handful of games on each system. It’s convenient to have my entire game library on one device, especially on the road.
