Devils advocate here.
I/O and storage in those media formats are kinda limited for video games.
Blue-Ray prob has enough storage (at most we could go for multiple disk releases) capacity but still you would have to copy the games to disk.
I think GOG is on right track on this DRM free keep on disk as long as you want no need to check with external servers to play them.

























yeah I put it on forms all the time not in transphobic way but like “who cares !!! And if so why the hell do you wanna know?!?”.
This on random stuff, for things like social or other studies where I clearly see the intent I usually put a seriously response, now on affiliate or library card why do you need that?
