misterfresh: - Is Micro SDXC fast enough for such a usage? I was thinking of USB because it has gotten faster. (....)
your USB 3.0 slot can provide you with 640 megabytes per second speed, which is much better than 60MB/s with USB2.0,
same for USB sticks, and I have found on two machines, that the SD card slot goes only a little faster than the fastest USB slot, the difference is that the SD card slot deletes files twice as fast, also it depends on file structure and cluster sizes,
SDXC 1TB, NTFS,16kB cluster, copying Tomb Raider Anniversary
up to 81MB/s (stable) writing through an SD card slot,
up to 78MB/s (stable) writing through SD USB 3.0,
up to 33MB/s (stable) writing through SD USB 2.0,
SDXC 1TB, NTFS,16kB cluster, copying Dragon Age Origins
up to 81MB/sec (average 50MB/s) writing through SD card slot, deleting files max 640 objects/sec (540)
up to 78MB/sec (~ 45) writing through USB 3.0, deleting files max 320 obj/s (300)
up to 33MB/sec (~ 24) writing through USB 2.0, deleting files max 302 obj/s (280)

misterfresh: - For the physical box production, I think it could be structured as an on-demand printing service. The producer (GOG or someone else) would have a website where you can print(....)
We could print store covers and game art on a4 printing paper and unofficial DVD covers, then smear it with wallpaper glue and spray it with a transparent varnish : D Some A4-size boxes are needed.....
