Well, I'd keep a careful eye about Nintendo, as many people have. Their consoles have been thrilling, but what their plans and "changes" to their next system people have seen stands against physical media and game preservation as a whole.
Those "Game-Key Cards" aren't such an "evolution" as Nintendo wants people to think and themselves claim it to be. I feel, in my perspective, and out of my own great concern, as others that stand for physical media and game preservation that share such concerns, not to mention game ownership protection, so to speak, they're just a mere repeat of what happened to certain games' discs on the Xbox 360 that seems to have full data/on-disc DLC on their games, but haven't; that content in them were locked, and only required a price to actually play them/download from said disc.
I read that kind of story before, but, believe me, it did cause problems to any that thought they had full games.
Why would any game company try to "evolve" their own physical media that speaks the polar opposite of preservation at the behest of game collectors and preservationists all over the world?
Regular discs and carts always work very well, their sizes of which do get increased from time to time, and preservationists have been fighting to protect them.
People that have heard and seen the truth about theses Key-Cards have caused them to be against Nintendo for their anti-game preservation actions, merely mirroring to what happened with WiiWare, DSiWare, and 3DS eShop only games.
Not only that, the way how these cares are, they're trying to create more repetitive steps to playing and switching between physical games numerous more times.
And, people also strongly fear that should Nintendo's servers for that system go off, regardless of any digital game getting delisted from the marketplace in and at any situation, all their Key-Cards are permanently useless. Not everyone has fast Internet connection speeds and routers.
Nintendo, turning a blind eye to gamers and game preservationists, indeed.
Honestly, I feel Nintendo's trying to bankroll the Switch's hybrid console blueprint success quite too much because of its same features... and present management's vision. And, what the successor system offers is still the same, bland experience, in UI, sounds, pretty much as the original.
Since the Gamecube, Nintendo's consoles had their own charm and senses of identity that stood them out as regular game consoles. The DSi was the first handheld to have that kind of charm and identity, and improved on the 3DS. The Switch lacks it, and so is that new system... well, even more, to be precise.
People are advising not to purchase the Game-Key Cards after this. I'm all for preservation, but given the severity of its situation, I'd advise not to. I greatly worry for those people saving physical media.
I pray for things in the gaming industry and the game preservation business to sharp turn a 180 for the positive...
