A:Answer If you buy the Nintendo Switch Online Subscription, you will be able to play NES, and SNES games through the apps the Subscription gives you. Unfortunately, unlike the Wii, Wii U, and 3DS, you cant buy Super Mario World separately on the Switch, you have to subscribe to the service in order to play the game. However, if you do subscribe, you are able to play a lot (and I mean it a lot) of NES and SNES games that are on the catalog, You also get them for free (if you are still subscribed to the service) and they stay that way until you cancel or stop auto renewing
