HOlding onto something as a Memento is nice, but it's not something you can really attribute much worth too. It's like a Beanie baby in that regard. Sure, there are some people who care, but most people who think a lot of this NFT stuff is dumb probably also think the prices being paid for physical collector stuff is dumb. It has value only to collectors. As a personal momento it may have sentimental value, but that's not really something that you need an NFT for. Even looking purely at something digital you could easily hold on to emails, screenshots, or anything of the sort. This isn't something unique NFT's bring to the table. Doesn't change that a game shut down isn't going to be able to make use of that NFT.

And the Diablo 3 market place was bad, but that had more to do with the insane rarity of item drops. Make getting gear as NFT's just as rare and hard to come buy, you are going to have the same insane prices regardless. NFT's aren't going to fix that problem, the folks who farmed Diablo 3 for items to sell are going to be the exact same folks that would have done it if the items were NFT's instead. Make drop rates reasonable, keep any kind of transaction fees between players reasonable, that is what would fix the issues with Diablo 3's Market place, to a degree. In all honestly, there are a lot of people who hated the idea even as far back as two that certain items were so difficult to come buy and there were certain people who were desperate enough to pay money for it. This isn't something the majority looked at as a good thing, they saw the people selling them as just as slimey. Most people kind of hate the idea of trading in game items for money regardless, just attaching them to an NFT isn't going to change their minds on the matter.

Even as ownership of something, I don't know how nescessary NFT's are. There was a concept that existed a while back where you would own the cards you played with in this online card game (I forget the name of it). Thing is, you could play those cards in any game set up to use them by anyone. It all used blockchain technology, and even if someone shut down a game another person could create a game using all those same cards. This was all before this NFT stuff. So I still sit here not knowing any actual use for NFT's in relation to gaming.
