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.
Fuck you Nintendo. Because if you lose or damaged the game card, making it unreadable by the card slot, you won’t be able to play the game. Due to the game card having the license that allows you to play the game. You’ll own nothing and you’ll like it, gamer.
