I don't think that preferring physical copies of your games in any way makes you a "collectard", and I don't think that anyone is suggesting otherwise. Buying games *purely* for shelf-candy is what makes you a collectard. Just about every game that I own, I have for a reason. Usually because I like playing it, sometimes it's because it has some historic significance or sentimental value. But having shit just because it's "teh rarez"? GTFO.
I used to have a LOT more games. And I am so much happier now with a slimmed-down, but more meaningful collection/library.
