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.
One of the things I really like about the Switch is that I can actually buy a whole physical game that doesn’t need an Internet connection. Sure, I have to check a website first, but I can at least curate my wishlist with games that are complete on cart.
At least them giving it a new name makes choosing games easier, I guess.
There will still be normal cart. With a day one patch or not.
