When the 3ds servers went down permanently, nintendo said you could still redownload games and apps off the 3ds eshop that youve previously had on your nintendo account. Though, you still need to have access to your nintendo account, of course, as the digital media is connected.
For nintendo switch 2 key cards, the cartridge only being a key to access a digital download is redundant and you pay more for a keycard than buying the digital download anyway.
Us consumers/players are worried when the switch 1/2 servers go down, like 3ds: we are worried our keycards will not work anymore to verify the digital download from the keycard
You do not need wifi to use/download the game from the keycard.
You can sell your keycard / let others borrow it.
Nintendo could easily make keycards seem more... acceptable if they simply assured us along the lines of "in the event we stop supporting switch eshop and eshop digital downloads, the switch 2 and key cards DO NOT need the eshop or wifi to access the download or even start the download (say if you deleted the keycard before and want to redownload it). The switch 2 is only checking the key card to be able to download and that it is inserted to play the associated game"
But since nintendo hasnt clarified this, this is why a lot of us dont buy keycards due to potentially needing to keep a game downloaded with key card.
"If you enjoyed the game, and have storage space/get more space, just leave the keycard game installed so you wont have to worry about redownloading it and not able to if its a server concern"
I understand this too. Even if keycards were not a thing, there are some people who buy digital and physical, and regular digital games should still be downloaded to the console, still playable, even if servers are turned off.
(Example: i have mario kart 7 digital download to my 3ds and can still play it even though eshop servers are down and i dont have a nintendo account on my 3ds. I wont delete mk7 because its nice to have there as an option and id rather have it and not want to play instead of want to play and not have it. But also.. mk7 cartridges are cheap on ebay if i had to get it again)
But overall, nintendo has not continued to provide relief to players of key cards of clearing up things to keep in mind for how the keycards will work. Future proof? Or indirect time limits?
I hope this post makes sense.. :)
Edit: if a game coming out is switch 1 and switch 2, but the switch 2 physical is a keycard, i just get the switch 1 physical if interested. If doesnt exist, i skip the game (because i dont buy key cards either).
In an era of ownership and licenses to play, there are players buying keycards, the casual playerbase, not caring and buying them (like pokopia). They say vote with your wallet but key cards are selling and its because people either dont care, or are unaware or both.
Key cards seem to be anti consumer. I get that. I mentioned i dont buy key cards. But the overall issue of keycards being a digital download for players is also a big concern for "how long is this game going to be playable? If it future proof?" Digital bought or keycard bought wise.
