Sounds like they're made with an expiry date then. All of my games work thankfully. Skylanders SuperChargers WiiU disc is an odd one though, the loading times tend to take a while to load up properly and freeze also. I'd say this is something that WiiU collectors aren't aware of because, it matters that the games actually work otherwise it's a waste of plastic and valueless (well, not entirely but loses a lot of its value). Nintendo is just stingy about paying for licences. They did the same on Wii which could have read DVDs but they decided it should only play Wii games.
