Blizzard could make their own second hand hearthstone marketplace if they wanted to. NFTs don't create that possibility. Blizzard judged that it's more profitable for them to be the sole sellers of cards at their price. While NFTs would enable secondary markets in hearthstone cards to exist outside of Blizzard's ecosystem Blizzard doesn't want you out of their ecosystem.
Furthermore even if they introduced something like that I highly doubt they'd use "some public blockchain" the risks from that would outweigh the benefits - they'd just make their own infrastructure internally.
I don't see a way in which NFTs solve a problem that can't already be solved more simply. After all valve secondary markets for games like TF2 have existed for more than a decade without needing NFTs.
You are kind of arguing my point. Blizzard won't do it because it loves exploiting their status against the player. But that's a point for nft-s, it would make it harder to exploit players. Yeah I agree it won't ever happen, but if it did, that would be a win.
Not “perfectly” well. There is the downside of cost. Without nfts they would have to invest in bespoke infrastructure for creating, storing, validating and trading the assets. With nfts, this entire infrastructure already exists.
I never said NFT-s were required or the only possible solution, I said that I don't think NFT-s in games are inherently bad or evil (which is a quite popular opinion)
