While this would be great, we'd have to stockpile on said media which is less convenient. Discs were great but they'd always get lost somewhere and/or used a lot of space when stacked.

I'd personally prefer to download the files on a hard drive which could hold thousands of games while saving space. Only problem being that these games would need to be transferred to an SSD for better read/writing speeds. On the other hand discs would only need to be plugged into a disc slot which may or may not seem very convenient considering how most laptops/PCs don't have those, meaning we'd need to buy these extra.

Either way having pretty discs with collectibles like in the good old days seems like a good idea if you're into that sort of things.
