the games you possess and the digital items you possess would have an independent record of your possession and continued access
if you did use a company's platform because of its convenient UI, even if you lost access to that company's platform you should still be able to access all of your games and items
in the Web3 paradigm and idea, the closed systems build themselves around open systems just to make them convenient, and aren't strictly necessary. the open system allows the records of assets to be tapped into and re-rendered in other games, or marketplaces. Think about it like Web 1.0 with updated technology and requisite pieces that were missing back then.
I’m not a fan at all of that kind of DRM. Cryptographically prohibiting the owner of the machine from inspecting what code is running on their machine is a different league than obfuscation but I’m pretty sure that’s where we’re heading regardless with DRM. PCs will become more like video game consoles in that sense.
Or of course, streaming cloud gaming, where your local machine is more of a thin client. In this case the NFT is really just a token you present to the proverbial gatekeeper every time you want to play. So you can still be blocked, but at least you’ll have irrefutable proof of which games you paid for and have an obvious case in small-claims court.
Especially the former will probably mean I’ll just completely quit gaming altogether.
the system would check your signature and/or check for current possession of the necessary NFT.
trusting a friend to experience that is up to the user at their own risk.
the game producer's goals are not really about preventing shared access any longer, as they are still selling items and doing things for creation of items (engagement), just like the most lucrative games already do now.
With online accounts you could prevent said identity from connecting to multiple online games at once but this is notably worse than old school physical games where you could have 3 games at 3 different friends houses while playing a fourth.
Makes me wonder if we should stop multiplying complexity beyond need and go back to cartridges except now they are $5 64GB usb drives.
A unique mitigation could be to raise the barrier of sharing, like not only could you check for NFT ownership, you could look for a purchase transaction on an NFT marketplace. So now the friends would need capital to wash trade that, and they'd have to beat the bots looking for low value bids, and they would have to unnecessarily pay for transaction fees.
Not advocating for that, but oh well the idea is out there now.
It becomes a long serial number that anyone who knows can transfer to another account.
But it wouldn't make sense to pay to transfer it over ($60-$300 gas fees) on an under $60 game.
I can see some real issues with your approach.
NFTs can't be used for products under a few hundred if you want to leverage the value as insurance.
the client and the server would be checking nearest nodes for the latest block height. so any mismatch would prevent the user from keeping a snapshot of an old blockchain state as the max height would be too different.
it is also easy to disconnect a user if the assets moved when reading the current blockheight. many web3 applications just keep a websocket open to several nodes, this is boilerplate code at this point. reading from a blockchain is free. many services already check for onchain tokens to enable or disable access, for several years now. you can try gaming them to trick for access and see if you find anything.
Even if a company offered a convenience service, the ideal implementation allows people to restore their account from the current function state onchain, which is what most web3 services do in an increasingly standardized and predictable way right now.
regarding the NFT's and where they store the images, many NFT classes have getter methods that tell enough about what the implementation of the digital item should look like, usually when I'm talking to people I get the impression that they haven't looked.
there are so many ways to do this right, even if they aren't passing muster right now.
