Nintendo implements a new feature on the Switch 2, exciting fans who feel like it's the return of a nostalgic DS feature that many have been missing.

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,

This appears to run similarly to the “Download Play” option for the Nintendo DS. For example, one person may own a copy of Big Brain Academy: Brain vs. Brain, but using the new GameShare option, your friends can jump in and join you to play, even if they don’t own it.
