They were observed finding one ROM on the Internet, ever. They do have their own emulator(s).
Nintendo is a bunch of humans. If my boss asks me to see if I can find the installer for an old version of our software, you can bet I’ll check anywhere before volunteering to go scrape old hard drives.
I love my Steam Deck. It’s literally beside my hotel bed right now, while the Switch is at home with two kids under 10. But:
If “I just want to pick up a controller after work and forget what Philip in Marketing said he thought the project was going to look like”, or “I want to buy games once and share them with my kids” or even “I’ll throw this in my bag to kill 20 minutes at the waiting room” are factors, the Steam Deck is very much not superior in every way.
Again. Love my Deck. Almost exclusively buy “Verified” games now. Halfway through a Nintendo game that somehow is easier for me, a software dev to find ajd emulate on Deck than on a Nintendo console. But the Switch has been a remarkable console to have in my living room. The first console I bought (actually now that I think of it, that my wife bought for me) since Wii and before that since PlayStation 2. I’m not really a console player. I have 1000+ games on Steam. Still Switch excels at many things and the sales figures should make that obvious.
