technically the same game / set of data as the one you most likely already have + Expansion Pass ON cart!
So as a german user I back then bought the - well - german (USK) version of the game.
I was quite surprised THIS complete version shares the very same set of data with mentioned german/european version, as it did not create a new icon on my switch. I was very sure it would end up as like as it did with Final Fantasy X/X-2 (completly seperate), but I was very wrong.
It also links me to my regional german eshop page of the game. So for europeans and most likely americans as well - seeking out the complete version on cartridge, this is it. You are pretty much able to 'upgrade' your cartridge that way without having to start over, if you prefer the dlc on cart.
Info: This is NOT from playtesting, but rather from watching.
I don`t think I have to comment anything about the game itself. It is a masterpiece.
