GameShare is a Nintendo Switch 2 feature that lets one player share a supported game so others can join in, turning a single copy into a session for the whole group. Nintendo lists it among a game's ways to play in two forms: GameShare with local users, for friends and family in the same room, and GameShare over GameChat, for players connecting online. Either way, a Nintendo Switch 2 system has to start the session, with its owner sharing the game so the others can join. Sharing over GameChat comes with a clear boundary: anyone who receives a game this way can only play it during the GameChat session in which it was shared, and the game is no longer playable once that chat ends. That makes it a way to play together in the moment rather than a way to lend a game. Online use, including GameChat, requires an internet connection, a Nintendo Switch Online membership and a Nintendo Account, while GameChat's video features also need a compatible USB camera. GameShare is not available in all countries. Support is decided game by game, and not only for new releases: some original Nintendo Switch titles have gained GameShare through a free update for Nintendo Switch 2, so you can often share games you may already know well. How a game uses the feature varies. In Super Mario Odyssey, for example, GameShare lets two people play together, one controlling Mario while the other controls Cappy, whether they share locally or online via GameChat. That kind of design suits cooperative adventures, party games and titles where a second player can contribute without needing to master every system. It is a natural fit for households where one person owns the game but several want to play, for introducing a friend to a series before they commit to it, or for keeping a long-distance game night going. Check each game's details for the ways to play it supports, since the shared experience differs from title to title.
