Super Mario All-Stars is the same as it was for the Super Nintendo Entertainment System. It includes Super Mario Bros., Super Mario Bros: The Lost Levels, Super Mario Bros. 2, and Super Mario Bros. 3.
Just like with the original release, all four games boast improved graphics and audio over their NES counterparts.
Unlike the just-announced Super Mario 3D All-Stars Collection, the Switch version of Super Mario All-Stars is not a limited-time release. It’s available now on the Switch eShop — but only as part of the Nintendo Switch Online Super NES Collection. It’s not available for purchase at this time.
Still, barring any unexpected shenanigans, it should remain playable for the foreseeable future. Stay tuned to GameSkinny for more Super Mario 35th anniversary news as it develops.
