How 'Doom' creator John Romero shaped video games and culture at large

Video game legend John Romero opens up about his tumultuous upbringing and how he went on to make his mark on the video game industry by pioneering the first-person shooter genre through games like Wolfenstein 3D, Doom and Quake. He joins Rebecca Zandbergen to talk about his new memoir, Doom Guy: Life in First Person, and how the video game industry has changed and shaped culture at large — from the relationship between fictional and real-world violence, to the conception of video games as an art.
