When choosing that account as the 2nd player for Diablo online, the game forces the author to link it to a Nintendo account (presumably to check for online subscription).

The author made a new guest account and didn't tie it to an account.

The author said it doesn't matter if the 2nd player's account/profile was tied to another Nintendo account.The author tried out the same thing with Mario Kart 8 Deluxe, and noted that 'you can play 2 player on 1 switch online, with just 1 online subscription.' But, this has been pointed out that this is offline local multiplayer, which is allowed.However, the author attempted to play locally with a 2nd player (on 1 switch), and found out the game is unable to go online with that 'user account', as it doesnt have online access.The author has read about the game that it would require the Nintendo Online Subscription to play online.Please save your hot takes, just knowledgeable replies, please and thank you in advance. I would love someone to explain clearly where this is going wrong, or what we haven't tried. No one but the main switch account can launch the game, though I could launch the game on my friend's switch from my external switch account, presumably because I own the game too, however in my launched game, the local online switch account for my friend's switch still couldn't join my game as anything but a guest. It forces player 2 to play as a guest and doesn't save their progress, it will allow no other user account to join as player 2, I also tried adding my own user account from my switch to my friend's switch (and I also own the game myself), it wouldn't let my external account join either. When trying to join a game on the character select screen, diablo says select a profile for for player 2, and every other account is greyed out. That same account is considered the owner of the digital copy of the game.

This switch has 3 local user accounts, one is linked online. There is one purchased digital copy of diablo 3 eternal collection on a switch. Ok so here's what we tried, and please respect that we're technically savvy and tried a lot of variations and spent hours reading internet threads trying to solve this yesterday instead of just playing the fucking game: Last updated at 14:00:17 UTC Weekly Help Desk RAGE Loot Thread Trade Thread
