When me and a family member were playing a game with our new black Wii U, it locked up and became unresponsive. The damn thing just would not respond to anything, I even held in the power button for nearly 20 seconds and it would not power down. I hated to do it but I had to pull out the power cord. Just wondering if something like this could lead to a glitch hack, or some sort of exploit, or is it just bad game developing by the game manufacturer?
