I'm not getting rid of my collection now or ever (if I can help it). As a gamer, I see myself as part collector. I've gone out and physically hunted for some of these titles, and even if I don't actively play them, the memory they invoke when I look at them is well worth keeping them around.
The same with my old PS1 games, I could never part with most of them because looking at them, holding them, and playing them invokes memories of my past that I remember fondly.
