This is just a suggestion, but do you see a market or chance for digital games keys or access to be rented out rather than being finally transferred via a sale? I don't know but if there are expensive games, maybe there is a market for something like game leasing or so?It just came to my mind so I wanted to share this thought with you.
Well of course, I kept trying to understand that it reminds me. Leasing!
The argument that developers would suffer from that is true though. If people can share a license via a smart contract, that would mean that developers sell less games. There might still be a market for game key rentals. It needs more thought though.
