I recently purchased a few Atlus games on the DS, one of which was Knights in the Nightmare. It came packed inside a cardboard box that held the actual plastic DS game case and a bonus CD. When I pulled out the plastic game case I noticed that the outside cover insert is completely damaged, they cut it a bit too large to fit and just jammed it in there, causing it to warp. It kind of pisses me off, Knights in the Nightmare will probably end up being rare (since it’s an Atlus game with a small print run), and I like to keep my games in good condition, especially the rare ones.
And it’s not just me, apparently a few different people have been having this issue:
And plenty more, just search “knights in the nightmare crinkled” and view the 6,000 or so results.
