Why Tim Schafer keeps remaking his classic games

Tim Schafer is smiling and shaking hands with a hovering crowd as I sit down next to him. A college student asks if she can talk with him later about his career. A fan thanks him for his work -- a library of iconic video games that stretches back to the early '90s. He takes the time to respond to each of them, encouraging the student and graciously accepting the fan's gratitude before sitting down to walk me through a demo of Full Throttle Remastered, an HD remake of one of his first games. I ask him if it was strange to revisit a game he created over two decades ago.
