I recall once I was playing OoT and I had just beaten the Fire Temple when the power went off. I hadn't saved in well over an hour. Yeah it was kind of irritating. But what can ya do?

I sort of like power outages so long as they don't last too long. I can play Game Boy or DS while I wait for it to come back on. It's most fun when the power goes off at night and it's pitch black and you have to use flashlights and have candles everywhere XD
