The name of the video: I WAITED 6 YEARS TO PLAY THIS.
Confession time: I am closet PewDiePie fan. When I saw that he was among the first to get an early look at The Last Guardian -- a game I've been waiting six years to play -- my first reaction was "why?"
But this makes perfect sense. The Last Guardian already has a core of fans who will buy this no matter what. PewDiePie has a different audience and that audience is tremendous. Getting Pewds to play a game is pretty much like getting your game on Conan O'Brien at this point.
