You may have noticed that your Xbox 360 games have recently arrived in crappier boxes. They look the same on the outside, but when you open it up and remove the disc, you'll see big holes cut out of the case's back with a weird "web" of plastic keeping the disc barely secure. It looks silly and makes the case bend whenever you try to open it, but Microsoft has finally revealed why the cases changed.
The new cases are supposed to be more environmentally friendly (eyeroll) and have also been made lighter to reduce shipping weight. They were designed by Viva Group in order to better perform according to Walmart's "packaging scorecard" initiative -- a scheme that aims to reduce packaging materials by 5% before 2013.
These cases are the new standard, so even though they feel flimsy and see unable to hold games in place, you can expect to see them shipped with all 360 games from now on. Nintendo has told Kotaku it will follow suit with its own reduced, lightweight packaging. Sony has not confirmed it will do the same, but said it was always looking to streamline its goods.
Silly business, but whatever. These companies have a pathological need to look like they're doing something for the environment, so it might as well be this.
