You can play one Nintendo Switch 2 game on multiple consoles with GameShare

The Nintendo Switch 2 has a new feature called GameShare, allowing an owner of one game to share it locally with up to three other Switch 2 and original Switch consoles.

It also supports online play with other players, including game chat functions. The feature will be compatible with select games, and so far Nintendo only listed Super Mario Odyssey, Captain Toad Treasure Tracker, and a couple others as examples.
