Had this from time to time and its a non issue. Blurays are pretty resilient I've never seen any disc take damage from this. Its annoying but I wouldn't worry about it too much.

Never had a loose disc issue, though I once ordered a copy of Nier Automata from Best Buy and the case was cracked in half lmao (the game itself was somehow unscathed).

Yea this seems to always happen with PS4 games for me too, even retail copies.

Thats due to the truck bouncing around causing major items to move. Doesn't take much for the disk to unhinge itself from the case.

I think it happened to me once, with RE7. Luckily the disc was not damaged at all, but it was annoying a bit. But still, for the last 2 years I went completely digital on all fronts, except the handfull of games I got as gifts.

When I worked for EB, we received games in boxes of 24 or 30 depending on the publishers. Generally, a fourth of the copies had the disc loose every time. Always on PS4, rarely on Xbox and Wii U.

It has happened but it never visibly caused any damage to my game at least.

I have certainly had this experience. It probably happens somewhere between 1/3 to 1/2 of the time. That said, it does not seem to be particular to PS4 games. I've had the same issues with PS3, PS2, Xbox (original), and bluray movies. Sometimes its just loose, but sometimes the spool is broken (which is definitely the much more frustrating scenario).

I will say that I've often (but not always) found that those cases that let go of their discs in transit tend to hold the disc less securely going forward. My guess has always been that there's an almost imperceptible difference in the measurement of the spool's cut that causes the disc to sit ever so much more loosely.

As to the damage, I've never had any issues with a PS4 or PS3 game and rarely with a PS2 or Xbox game. However, I have had several bluray movies suffer scratches due to this phenomenon (which shocked me, honestly, given the density of the discs plastic). Like abronn627, I also used to work for a video game retailer, and, in my experience, scratching BDs was a much more difficult proposition than scratching DVDs. Through this job, I actually found that much of what looks like a scratch on BDs can actually be wiped away with a microfiber cloth - in case that information is ever useful to anyone :D

Had some cases of loose disc, but not sure from mail order. Still BD is quite hard to scratch so I hadn't issue to play a single game since PS3.

The only disc I ever saw scratched the person really tried to do it.

I don't think it has happened any time recently, but I remember it happening quite often at some point. Never had any real problems because of it. In fact, I don't think it has caused even a single scratch, at least as far as I can see.
