I used to collect computer games... I have more games than I can play. I've stopped now, but I still haven't gotten to play all of my games :-/

I think the "collector-obsession" is what fuels most of the p2p-torrenting world, because there's no way most those people ever consume that much media.

When I was a kid, I collected comic books and comic book cards. I was generally after the art on the cards, but I did enjoy the stories in the books.
