Due to the whole delisting paid games thing, I've resorted to creating a product on Patreon and selling there. A Patreon sale basically allows a Patron to pay the price then either get access to a file or link or something else digital, but does not make them an account Patron.

This means that setting up a Patreon link doesn't work for these as it requires both a membership and to hit the required pledge amount but a sale counts as neither even if the sale amount is equal to the pledge requirement.

I then looked at External keys, but the whole thing makes zero sense.

Basically, I want to be able to sell and the customer gets a key they can use to download and retain access to the game. It can be done by manually assigning keys, but that means the customer has to wait for me to be online and adds a lot of administrative work. I could just link directly to a download file, but that also means having to update the file address with every update and as far as I can tell, there's no way to automatically restrict access on Drive with a customer list from Patreon. I'm trying to make whatever solution be pretty much automatic but also safe for both myself and the customer.
