actually does have some value to it in the form of sequels. they can say "Heartstone is over, we're going to Heartstone 2 and your cards are transferred to that."

this is probably done easier through NFTs/blockchains because the tech for that will be more consistently the same as opposed to a 5-10 year old game. there's definitely an element on this which would make the transfer of data easier. some cross-game integration can also be done with this, like Gwent can have a game of its own but you can play with the actual cards in The Witcher 3 as well.

all these companies already have their own account systems that can track what you do in one game and give you stuff in a different game, they dont really need the blockchain for that
