The Web3 part of this would be that no company needs to be responsible for the database that says that a player is in possession of a particular item. The fact that limited cooperation between companies is needed is what could allow the adoption of standardized schemas.

I'd be curious if even that would be so simple. There could be competing blockchains or types of NFTs. You might also get into the situation where instead of every company building the software to verify ownership they just pay specialized companies.In that situation Web3 technology isn't really all that different than a company building a virtual shop API. A company like Valve could probably do this better than Opensea could and without all the extra Web3 technology.
