The Nintendo Online Expansion Pack is an add-on to the Nintendo Switch Online subscription service that was released on October 25, 2021. It includes access to classic Nintendo 64, Game Boy Advance, and Sega Genesis games, as well as select DLC for games like Animal Crossing: New Horizons, Mario Kart 8 Deluxe, and Splatoon 2. The Expansion Pack also offers additional features, such as access to add-on content at no additional charge and the ability to play classic games with newly added online play. The Expansion Pack is available for purchase as a 12-month membership for $49.99 USD, or as a Family Membership that allows up to eight people to share the benefits for about $10 per person per year. Some people have criticized the Expansion Pack for being a cash grab and not offering as much value as similar services from other gaming companies.
