The commercial version of Final Fantasy X | X-2 HD Remaster requires you to insert the game card to play X-2

As you already know, the commercial version of Final Fantasy X | X-2 HD Remaster in the US includes Final Fantasy X on a game card and X-2 as a download code. Now, here is where things get a little annoying. Even though X-2 is completely downloaded, you can not play it without inserting the Final Fantasy X game card into your Switch. A minor nuisance, but it stings even more for the fans who hoped that both games were played on a card in the first place.
