The changes I’m not 100% certain on. I’m assuming if you modify the Switch in some way whether it be software or hardware related.

So unlike most Switch 1 Games or even a DS cartridge for example, the full game won’t be on said cartridge and you will have no choice but to download the full game.

And you still have to download the entire game. Not to mention that they basically said you don’t own the game, just a license to play it.

From what I can recall, they I believe announced a change to their terms and conditions stating that if you make any changes to your Switch 2, they’ll brick the console itself. They also said that if you buy a physical copy of a game, the cartridge won’t have the game in it but rather a game key
