Game-key cards are different from regular game cards, because they don’t contain the full game data. Instead, the game-key card is your “key” to downloading the full game to your system via the internet.
Pay a premium for a physical copy of your game, and the cartridge may not contain the actual game. Only on Nintendo Switch 2.
Thank you for the clarification!
I still don’t like it.
Me neither. It’s basically a download game but with physical DRM in the form of a cartridge. The age of genuine physical game ownership is toast.
