So for my 1,000th post (

), here is a stack of PS3,PS4, Xbox One and Blu Ray NTSC cases
They're all kind of mixed in, but you can see that Blu Ray cases are significantly slimmer than PS3 and PS4 and even a little trimmer than Xbox One. The sleeve dimensions (as previously noted) are also very different.
All blu ray cases are the "slim kind" though they do have multiple discs. The only thick Blu Ray case is Hellsing (in between Kingdom Hearts and Resident Evil), as that case has 5 discs inside.


I have a few hundred Blu Rays, and the smaller size is, without a doubt, the standard. For USA anyway. Also, NA cases are much rounder than the boxy PS cases
