So, for the first time in about two months, I decided to give my copy of Spider-Man: Edge of Time another chance. I pulled it from one of the cart cases I keep it and all my other DS/3DS games in, put it in the 3DS, and sadly saw that the 3DS wouldn't detect it. I have no idea what's wrong. I've tried powering off and powering on the 3DS multiple times, both with and without the game in it, and no go. My 3DS has no problems reading any of my other DS/3DS games, and I've kept the game in the same protective plastic carrying case as all my other games. It's also never been in water or anything similar. Anyway, fate has it that this was one of the few games I got insurance on at Gamestop, so replacing it won't be a big deal. However, this leaves me a bit curious and concerned as to what could have caused this in the first place. If there's something I'm doing wrong with how I store my games, I want to know so I can stop and prevent this from happening to my other uninsured games. Any feedback is appreciated!
