I was thinking that it might make more sense for libraries to be stocking 'culture' games over whatever the flashy game of the month is. But then I realized:
a) who are they to judge the value of archiving a game? Quite the pretentious attitude imo. Not to mention I don't think the average library staff is remotely qualified to do so.
b) Libraries stock the latest pulp paperbacks and trashy romance novels. I refuse to believe that bestselling games fall lower on the art scale than a lot of these.
