I'm glad that used games will come to an end. Hopefully it will lead to better quality games. Besides I'm all for the end of physical media. All of my music, movies, TV shows and comic books are now bought in digital formats and I have no regret. I have loads more shelf / storage space, I get the items quickly and can enjoy them faster than if I had to go to a store and wait in line, blah blah. I mean you can get same day comic books before the comic stores even open, same goes for music and movies (if you don't want to go to Wal Mart that is, which doesn't sell explicit music anyway).
You say that, but come the day some computer hacker takes out his failed physical existence on a companys server and wipes all it's information, you'd change your tune. I prefer physical media because it's a physical copy on hand without relying on third parties such as steam or a hard drive to ensure the information contained works. Also, what's so bad about used gaming? If it weren't for used gaming, I would never have found half of the games that I know and love. Unlike derptards, I don't buy games because they look like 'l33t 5h00t3r br0', if a friend has a game that looks appealing, I ask about it, do research, and then shop around for a bargain price. I'd much rather go through 'long lines' than deal with the reliance on a hackable machine holding my information.
As for running out of storage space, I don't see that as a problem. I think everything will be cloud based like Amazon and Apple. When I watch a movie on my Kindle I simply delete it and I can always download it again from Amazon later (or I want to say you can stream your purchases from the Cloud. I know you can when you rent movies, but I haven't tried it on a purchased one yet). Same for games. I'd assume if I buy a lot of games (digitally) on the next gen Xbox I could delete the ones I don't play and download them again from the cloud should I want to play them.
Again, your reliance on other services to maintain a product you owns data is laughable.
I'm not a paranoid parrot in this case, but prevention of problems is helpful. Your hard drive corrupts and the data is unsalvagable, you conveniently have the info on a floppy disk to use. (Yes I know not many people use FDs in this age, but that's not the point. I find the over reliance on digital information over a hard source to be bizzare and causing complacency amongst people. So assured that their precious Apple/Steam/Whatever is infallible.
I'm probably alone in my cautious attitude around here, but I feel it's a very sound and understandable caution.
