The fact that you can digitally share every single one of your games with your friends >>>> Being able to save $5 at gamestop of the retail.
But you can't.

You can only share one game, once, and you can never get it back again...and in order for that to happen, they must be on your friends list for more than 30 days

and even in the murky "family plan", only one other person can play from your shared library at any given time
Have fun creating schedules with your friends on who gets to play what and when


how is this any different than a disc based game? Can you play the same disc on 10 different systems at the same time now?
You don't have real game sharing
??

how do you "share" a disc?
