What really made me a fan was Let's Play Bunny Must Die: Chelsea and the 7 Devils. It was informative and Naka was pleasant.
Under an alternate account, he is now playing the Bunny portion over again. However, this time he is doing it without gears, dashboots, or wall jump boots. (Plus, annotations instead of audio commentary.) He can't even move backwards without pulling off special tricks!
One of these days I'm going to have to try that game out :P
