Sure sure, with disks it is the way to go. On the SNES era we had these paper boxes that did not last at all, I used to keep them aside and the cartridges in a pile. But I used to sell the old console when I bought a new one, or donate it with all games. Owning more than one console was such a foreign concept to me at that time.
Now I have WiiU, Xbox One and PS$, they all use disks, so, what can I do but to keep the cases?
