Internet in homes is pretty ubiquitous, especially among those who can afforda Nintendo Switch or a Playstation 4 in the first place, so the chances that the person buying the game doesn’t have access is pretty darned low…
…unless you’re in the hospital for a cystic fibrosis tune-up, and only one of the two household Nintendo Switches has copies of Super Mario Party or Mario Kart 8 that are up to date. And the hospital’s guest internet, which is perfectly useful for downloading email and surfing the web, has decided it won’t let you connect to the Nintendo game servers. And driving 45 minutes home just to update the games really isn’t an option.
I like it when technology is created to do unexpected things.
