Our very own Paul Miller told you how StarCraft changed his life (and more recently, how much he's been missing the game), but you couldn't ask for a better primer to the competitive video game subculture than PBS Off Book's latest episode. In "The Rise of Competitive Gaming and E-Sports," our favorite new YouTube series traces the roots of today's most popular multiplayer titles back to the arcades, accessibly explains the four most popular genres (shooter, real-time strategy, MOBAs, and fighting games) and — through testimonial and loads of footage — gives you a rough idea of what it looks and feels like to be part of the video game tournament scene. Watch it below.
