I am not a blockchain or NFT expert by any stretch of the imagination. But I often hear about blockchain or NFTs being leveraged for the purchase of in-game items.

But are there more profound use cases? Game preservation is something that comes to mind for me. So for example, I downloaded P.T. on PS4. I still have the local copy tied to that machine, but now Konami has removed the game from the PS Store. So if I lose that PS4 or it breaks or whatever, I completely lose access to that game.

Notwithstanding the fact that actually playing P.T. in future would rely on hardware that can run it, I'm very conscious of the fact that in some sense I don't actually "own" P.T. - I have some sort of temporary/ephemeral access that is vague, undefined, and subject to the publisher's whims. This is also true for something like Game Pass games or potentially any digital download of a game.

If I take a physical copy example: I own several Saturn games that, right now, I have no way of playing. But there's no sense in which I've lost access to the media itself, because I own the discs - they are in my physical possession. I can theoretically access them at any time.

This longwinded comment is my way of asking: can blockchain technology be one way to facilitate better game preservation in the future? I think that could probably be its own story, but I find it interesting to consider.
