If you make a backup of a $15-$20 item that is ok? but a backup of $60 item is not?
As for backing up to the hard drive that is a must for someone who travels with their box. A friend had his luggage lost. $200 (XBox1) console and another $300 of games, ouch.
Because backing up DVDs and CDs can be done without hacking anything. To back up a game for the xbox 360 you have to go to a lot of trouble and for what? Making sure your games don't get sractched? What I'm saying is the games are abundant and are plentiful in supply where as some DVDs of Cds could be hard to come by.
Why would you need to back up the x360 games. Sure some may need to but most people who voted in this pole don't own the games.
As for backing up on a HD, I can respect that. It certainly improved some games e.g kotor, halo and gta with faster loading times.
