So… Almost every single video pre switch besides speed running videos? Where the fuck else are they supposed to play them? By the time “let’s plays” we’re popular on YouTube we were in the time of the Wii or even passed it. And even if they didn’t emulate, they’d have to have bought the console off eBay where Nintendo makes zero money from the discontinued consoles. This is literally just control for the sake of control and it’s why I hate Nintendo.
It’s more about accessibility. It’s not like they make the games anymore and the emulators they have on the Switch are lackluster. You could buy shit on eBay but if it’s a super niche game it’d probably cost a lot of money. Money that doesn’t go back to Nintendo. It’s not like they’re going to lose money for someone playing a super rare game on an emulator.
