As a gen X'r, having a physical library is not nostalgic, its mandatory! I come from an era that if its not tangible it doesn't exist to include my video game library. Do I own digital copies of games and DLC of coarse, but truth be told it bothers me that I cannot physically see it on the shelf. Sure I have games that do nothing more than consume space because online support was dropped years ago, but my hard-earned dollar is on the shelf and not lost in cyberspace... However, does having the disc really mean anything other than aesthetics? 

Many tend to confuse owning a game with owning the right to access and play a game, even if you have the disc or cartridge in-hand. Some will call it semantics, but tell that to people getting banned from online play. As hard as it may be for some to comprehend, when you buy a video game physical or digital you are not purchasing the game, you are purchasing the right to access or play that game, UNLESS the EULA (End User License Agreement) stipulates otherwise. Yes folks there is an inherent EULA attached even why you buy a physical disc between you and the publisher. 

So what does this all really mean? "Nothing" as funny as it sounds, in reality my shelf is a library of nothing but licenses to play games, you go to your local video game store and buy, sell, and trade licenses to play games.... Cause we the players and retailers do not own any games........... funny.
