What's the longest you've ever left a game console on? It can include time you weren't actually playing on it.
I've left my GameCube on for over 24 hours a few years ago, because I wanted to go to sleep, but I wasn't near a save point in Metroid Prime to where I could stop playing. But the longest I've left any console on is days, I left my 3DS on for over a week without realizing it. I just kept putting it into sleep mode when I was in the middle of something. I realized eventually I hadn't even turned it off for over a week. But I suppose it's not as big of a deal with the 3DS as it would be for any home console, which could easily overheat if kept on for too long.
