It feels like it would kind of defeat the purpose. If you like the ritual of physically picking a game and putting it into your machine, there are more practical ways of going at it, like those NFC card-based systems like Zaparoo. If you like having a physical collection, it seems to me that having a bookcase full of labels made with a home printer and with none of the legitimacy of them being “the real thing” would feel rather empty. You can’t legally resell it or lend it to others and if you care about preserving the game without being dependent on an external service that can go down at any time, you’re probably better off keeping several backups of your hard drive than counting on flaky recordable media (hard drives don’t last forever either, but you’re more likely to regularly check on the health of a couple of hard drives than potentially hundreds of BD-Rs and SD cards).
Basically, very few of the advantages of physical media would end up remaining.
Huh, that’s interesting. I already expressed my thoughts on consumers making their own physical media in another post (tl;dr: I don’t think it makes much sense), but if there are recordable discs with lifespans comparable with pressed discs, maybe a print-on-demand service could be a solution for developers that can’t afford to order a batch of a thousand discs and cases and rely on digital distribution because of that.
