Advertisement Nintendo Switch Online is a subscription service that currently allows users to get hold of a wealth of SNES and NES titles from classics such as Super Mario World, to more obscure games like Pop’n TwinBee and Demon’s Crest. The service is available for £3.99 a month or £17.99 a year, and alongside an expanding library of free retro games it allows Switch players to play online. The Nintendo Switch has been the best-selling console for the majority of the last two years, leading the market for 23 months in a row. The release of the Xbox Series S|X and PlayStation 5 in November put an end to their dominance of the hardware market however.
