As Nintendo preps for the June 5 launch of Switch 2, gamers are buzzing about the new Game Key Cards. These physical cards won't hold game data; instead, players must download the titles online. While some see this as a step forward, concerns about game preservation and reliance on servers loom large. Nintendo's first-party games will still use traditional cartridges, but many third-party titles are going digital. With launch day approaching, players are eager to know which games will use these cards and which will stick to the classic format.
