Unless we're talking Switch 2 game key cards. Those are just downloads you can trade. But at least Nintendo puts all of their own properties on full carts rather than game key cards (Pokopia aside; Gamefreak and Pokemon are technically not Nintendo).

I don't drink. But also don't use the switch. Also I said most games are codes in a box with no cartridge. She only has one damn thing on a cartridge. Considering how much we paid for that tiny console and how expensive the games are, I wouldn't touch those with a 10m-pole. Would pay a bit more and get a steamdeck if I absolutely HAD to be mobile.
