> NFT's provide a mechanism (as I understand it) for royalties to creators. If this is implemented for games, then second-hand sales are entirely possible for a digital game. I don't think that's possible today.

There's nothing preventing this today, and nothing NFTs solve that would force those features to be supported. It can be done with a centralized ledger (a database hosted by the marketplace implementer, like Steam). I don't see the incentives for the marketplace platform to implement itself in terms of NFTs.

However, I could see game developers and gamers have uses for NFTs using a decentralized ledger to cut out the marketplace vendors from the transactions (or requiring transactions take place only on their systems).
