My main problem with this "you can own a video game asset!" argument is that you just don't.<p>You own a token on the blockchain that currently points to something. Tomorrow, it could point to something else. Let's take the "only sword that can kill a certain monster" thing, and have a look at the parts involved.<p>The parts are:<p>- The token on the blockchain
- The art assets of the sword
- The stats on the sword (including what it can and can't kill)
- The list of games where this sword is a valid item<p>Of those, the NFT will only let you own or in any way control the first point. Let's say I get The Sword Of Dragon Murder in game A, and it is currently also accepted in game B. Woohoo, metaverse! The company in control of game B will control what it looks and sounds like in game B, and they will also control what it does there. Maybe it <i>only</i> kills dragons there, but the game has no dragons? It doesn't even need to be called the same. For a joke, they could have it display as "The Toothpick of King Arthur" and using it will have your character do a "pick your teeth" animation. Zero dragon murders to be had, no matter what you paid for the NFT.<p>Even worse is that you can't even control what the item does in the game you got it from. At any time, they can change the art assets so it looks like any ordinary sword, and remove the dragon murdering stats.<p>We even see kind of that in games now: Power creep.<p>When the next expansion comes out, your current gear is likely to be outdated, and you have to grind for the new stuff (or "microtransact" yourself up to date), and it doesn't matter if it's an NFT or a regular entry in a regular database, because your old stuff is still crap in the new area.<p>In your favorite MMO, take a five year old "best item" and try to sell it on the auction house. You won't get "best item" sort of prices. Why would that magically change with NFTs? Why are they exempt from this?<p>It seems obvious to me that the people talking about NFTs and secondary markets in games have not played any MMO for any length of time, or they'd know about nerfing and expansions.
