7. Super Mario Bros. 3 The Magic Flutes
http://youtu.be/wz3BuYYhnn0 Anyone who's anyone knows about Mario 3's Magic Flutes easter egg and practically anyone who's anyone has exploited their magical world-skipping powers in the past. However, even with the magical flutes, I don't anyone perusing this piece will have devoured the game as fast as
Zero1two, the speed runner on display above. Blink and you'll miss half a level; yawn and you'll miss entire worlds. In fact, you probably couldn't even call the above clip a speed run as it probably represents months, if not years of practice and planning. Still, it's pretty god damn impressive.
