You have an expectation that NFTs would surely instantiate objects, I see no reason for that. Moreover I see no motivation for game companies to keep support.

You have an expectation that NFTs would surely instantiate objects, I see no reason for that. Moreover I see no motivation for game companies to keep support. Imagine you have an NFT for, say, a gun, let's go with AK47 because of its popularity, and say it unlocks it for the current Call of Duty (whatever that is now). Why would Activision make it work with the next CoD? Is it supposed to work with Battlefield too? Is there anything stopping people at Valve from giving you a cosmetic if you validate it, if they so desire?
