Re: Physical or digital copy?
Anytime you register a game on Origin it then becomes a digital copy, thus you shouldn't need the physical disk to run it. I know I have disks for Mass Effect 1,2, and 3 and all are now on Origin and the disks gather dust on the shelf while I play games. Up side is you don't need a drive and you don't need the disks....down side is if something happens to Origin, you lose access to the games until you get it fixed. I also find it helpful to have either a big HD for the games, or to have a large USB stick to make a copy of games from the Origin drive. That way you can copy the games to a backup and if you want to install the games again and don't want to download 25 gigs of data, you simply use the backup to copy it back to your use drive and tell origin to install and poof game is back no large download needed.
I personally have moved over to pure digital for game purchase, I don't even bother with physical disks for new games. I use whichever online system is needed and just buy the game and install online.(Which all the companies love cutting out other retailers and keeping that profit)
