Do You Really Own That NFT Sword? What 'Ownership' Means in Games

Every gamer has a story like this. A favourite online game shuts down, and with it goes a character you spent years on, a rare mount, a cosmetic you paid real money for. Nothing was stolen. It simply stopped existing, because it only ever lived on someone else's server.

Blockchain games built their pitch on that pain. "True ownership" became the slogan of web3 gaming: put your items on a blockchain as NFTs, and nobody can take them away. So, years into the experiment, is it true? The honest answer is partly. To see which part, you need to know what an NFT actually is.

What an NFT really records

An NFT (non-fungible token) is an entry in a smart contract. The most common standard for one-of-a-kind items, ERC-721, was finalised on Ethereum in 2018. At its core, it records two things:

• a token ID, a number that identifies the item within its collection, and
• an owner, the wallet address that currently holds it.

The standard also lets each token point to a metadata file: usually a link, called a token URI, to a small document describing the item's name, image and attributes. That link is where the illusion of "owning the sword" begins to crack. In many collections, the metadata and the artwork are not on the blockchain at all. They sit on a company's web server or on a file-sharing network such as IPFS.

So what you own, in a strict and slightly unromantic sense, is the record that token number 4,812 belongs to your address. That record is genuinely yours. Nobody, not even the studio, can move it without your keys (unless the contract was written to allow that). The sword's look, stats and usefulness live somewhere else.

What the blockchain can't promise

Here is the list of things an NFT, on its own, does not guarantee:

1. That the game will keep running. If the studio shuts the servers, your sword's token still exists, but there is no game to swing it in. Several web3 games have closed since 2023, and their items became tokens with nowhere to go. 2. That the item will keep its stats. Damage numbers, rarity effects and drop rates are usually set by the game's code and servers, which developers can patch at any time. 3. That the art will stay online. If the metadata server goes down, the token may point to a broken link. 4. That you can use it elsewhere. Other games have no obligation, or easy way, to recognise your item. (We unpick that promise in our interoperability explainer.) 5. That the studio can't block it. Games can still ban accounts, or refuse to load items flagged as stolen, through their own servers and terms of service.

What an NFT does give you is real, though: a public record that you hold the item; the ability to sell or give it away without the studio's permission (if the game allows trading at all); and a record that survives even if the company disappears.

How it compares with what you already "own"

It helps to compare blockchain items with the digital purchases most gamers already have.

Steam. Valve's Steam Subscriber Agreement, the long document almost nobody reads before clicking "accept", says plainly that games and items are licensed, not sold. You have the right to use them under Valve's rules, and Steam's Community Market lets you trade many in-game items, but every trade happens on Valve's system and under its rules.

Console and mobile stores. Similar story: digital games and in-game currencies are licences tied to your account. If the account is closed, so is your access.

The law is catching up. In 2024, California passed AB 2426, which requires digital stores to make clear when a "purchase" is actually a licence that can be revoked. It took effect in 2025. In Europe, the Stop Killing Games campaign gathered more than a million signatures for a citizens' initiative asking the EU to stop publishers from making paid games unplayable when they end support.

Notice what these fixes have in common. None of them requires a blockchain. A law that forces honest labels, or a rule that a paid game must stay playable in some form, would protect players whether their sword is an NFT or a row in a company database. Blockchain supporters argue that tokens make such promises enforceable by code rather than by courts. Critics reply that code can't force a studio to keep a game running.

In other words, the problem blockchain games point to is real. Traditional ownership in games is weak. The question is whether NFTs are the best fix, or just one of several.

Where 'true ownership' is really true

There are cases where on-chain ownership is genuinely stronger:

• Fully on-chain games, where the rules and the items both live on the blockchain. Here, the item and its function can't be separated by a company. (Our Dark Forest story explains how that works.)
• Items whose metadata is stored on-chain, so the art and attributes can't vanish with a server.
• Open trading, where you can sell an item to another player on any compatible marketplace, not just the publisher's.

And there are cases where it is mostly branding: a token in your wallet whose meaning is entirely decided by one company's private servers.

By the numbers

• 2018: ERC-721, the main standard for one-of-a-kind NFTs, is finalised
• 2: core fields every ERC-721 token tracks: ID and owner
• Jan 2022: Moxie Marlinspike's shape-shifting NFT experiment
• 2024: California's AB 2426 passes; it takes effect in 2025
• 1 million+: signatures gathered by the Stop Killing Games citizens' initiative

WGC's take, and what to watch

"Do you own it?" is the wrong question. Better ones are: What exactly do I own? Who can change it? What happens if the company goes away? For a blockchain item, the honest answer is often: you own a permanent record and the right to trade it, while the studio still controls what it does. That is more than you get with most skins. It is also much less than the slogan suggests, and players deserve to know the difference before they spend money.

What to watch: whether studios store more of their item data on-chain, whether laws like AB 2426 spread, and whether any game, blockchain or not, commits in writing to what happens to players' purchases when it shuts down. That last promise would mean more than any token.
