Nintendo launched a new membership service last year, the original Nintendo Switch Online members can be upgraded, and the premium members mainly play some classic games such as N64 and MD on some old platforms, such as Mario Golf, Mario for Paper, Banjo Bear Adventure, etc. Now upgrading your membership comes with the added benefit of getting some DLC for free.
According to official sources, the first DLC was "Collection! "Happy Home Paradise" of animal friends. It also delivers the Booster Course Pass for Mario Kart 8 Deluxe Edition and the Octo Expansion Pack for Jet Fighter 2, which contains new levels for multiple single-player campaigns.
These DLCs, which used to be paid for, are now available for free after upgrading their membership, a perk in itself. Players don't seem to buy it, though, because these are very old DLC, and a lot of people have already bought it. Nintendo often provides some outdated things, will free games are also some old, many people do membership just for the Internet service, for a little giveaway, it seems that it is not worth upgrading.
