You might think that seeing the end credits of a game means you've totally mastered it, but for Runnerguy2489, that isn't anywhere near satisfying enough. Nope, this dude doesn't consider a game "done" until he's finished it blindfolded - and not just finished, but totally busted open with every item collected and quest fulfilled.
That's exactly what he did with The Legend of Zelda: Ocarina of Time. Not content with taking the game apart with the use of his eyeballs, he 100 percent finished the N64 classic with all mini-games completed, every piece of heart collected and all of the Gold Skulltulas killed - all whilst totally devoid of sight thanks to the cloth bag on his bonce.
It's not the first time we've seen this kind of tomfoolery attempted - earlier this year, Mike Tyson's Punch-Out!! was bested by a blindfolded pugilist at Awesome Games Done Quick 2015 (incidentally, Runnerguy2489 played through the opening three dungeons of Ocarina of Time at the same event and helped to raise $1.5 million for the Prevent Cancer Foundation).
Compared to Punch-Out!!, Ocarina of Time is a much more challenging undertaking, with a massive, largely open world to explore and plenty of opportunity to get hopelessly lost. That's why this attempt took Runnerguy2489 a whopping 103 hours, 10 minutes and eight seconds, although he also spent a large amount of time familiarising himself with the game prior to taking on the insane challenge.

This is the stuff that legends are made of, indeed.
