Are there other games that support simultaneous local+online multiplayer on the Nintendo Switch?
Solution 1:
Diablo three also offers simultaneous local and online multiplayer, though definitely not a game for everyone. I would suggest searching for local multiplayer or online multiplayer Nintendo Switch games and then doing some more in-depth research.
Also, Minecraft supports simultaneous local and online multiplayer, so long as everyone you want to play with has a Switch Online account. You could play survival or party up on servers.
