Nintendo president Satoru Iwata wasn't able to attend this year's E3 due to health problems. They were kept vague at the time, but we now know what the concern was, and it sounds bit more serious than first thought.
I can see where mintyfreshmango's Zelda and Dark Souls crossover is going. The Moon from Majora's Mask would actually fit right in as a boss and the warriors of sunlight would find themselves in a tight corner really quickly.
You can't argue with MATHS though. Looking at Mario's height and game maps someone's calculated the distance traveled. The Plumber also swam a distance equal to about eight laps of an Olympic-sized swimming pool. It felt like so much more at the time.
