Aside from the paid Switch 2 upgrade packs that add extra content and graphical improvements, Nintendo is releasing several free Switch game updates to add a handful of Switch 2-specific features and improve performance on the new console. Third-party game developers will presumably be able to release these kinds of updates as well.

The Nintendo Switch 2 will be able to play most original Switch games without any issues when it launches on June 5. According to an update from Nintendo, most big games and all first-party titles (with one tiny exception) will work on Switch 2, though you might need an update or an old Joy-Con.
