Nintendo has been slowly but surely fleshing out the number of games available, now including Game Boy and Game Boy Color titles, and we've pulled together a complete list of all the titles you'll get when you subscribe to the service – including the most recent additions as well as the bonus SP iterations of certain games. Nintendo Switch Online had a slow start initially, but with the introduction of SNES games, we've seen added value coming to the service which better justifies the asking price. We've updated the lists below with the available and upcoming titles.
Update: Nintendo has announced that Game Boy and Game Boy Advance games are now available to Nintendo Switch Online and Expansion Pack tier subscribers respectively.
