Nobody with taste wants game key cards.

Hey, if Pokemon fans want to hasten the death of actual game ownership, that's on them. Just don't come crying to the rest of us once stuff gets de-listed and services shut down.
As for the news itself, from all accounts this is the rare actual good Pokemon game these days, since it was made by someone other than Game Freak. We should always champion when a good game sells well. Doesn't interest me in the slightest, but good on them.
