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 from each system. It’s convenient to have my entire game library on one device, especially on the road.

I use my Steam Deck primarily for emulation, especially Nintendo IP. NDS, 3DS, N64, Gamecube, Switch. It’s the best Nintendo device that I’ve ever owned and it hasn’t been bricked or even threatened with such.

No link to said game?

Tell that to Nintendo and their fans.
