I’m assuming the author was thinking Minecraft with the kid’s friends would be Peer2Peer or something. I doubt Switch has the power to host a Minecraft server, but I might be wrong.

See Smash, which is entirely Peer2Peer for the main gameplay, but requires a Switch Online membership to play for… what exactly? Hosting a database of player ratings and using it for matchmaking? There’s probably one server rack on each continent running the entirety of Smash online.
