Update thanks to thethatfox:
Physical game cards may also not actually contain the game:
Nintendo Switch 2 Game-Key Card Overview
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.
Update 2: There is probably a difference in Game-key cards and card that contain real game data. So we don't know right now how often these game-key cards are used or if nintendo is using them.
No duh, digital games should be cheaper.
They aren’t paying to manufacture the disk/card and don’t have pay to ship it to stores.
What that doesn’t mean is that digital games be used to artificially inflate the price of physical games.
Which is what Nintendo is doing.
Yeah this isn't "digital games cheaper" but more "physical games more expensive".
It needs to be a lot more cheaper, since you don't actually own the game.
It doesn't cost $8 per copy to manufacture. I can get a writable 64GB SD card delivered to my door for less than that. And a plastic case is pennies to manufacture.
It's more about preventing people from trading or selling games with other people after they've finished playing them.
