His father used to tell him that sitting in front of the computer, playing video games for hour after hour, was a waste of time. So Cody Altman didn't quite know what to think when a college from halfway across the country called to offer him a scholarship -- for playing video games. "Honestly," he said, "I was skeptical." The young man from Anaheim changed his mind when he learned that Maryville University in St. Louis had an e-sports team with a coach, daily practices and league matches against other schools. Two years later, Altman -- who goes by "Walrus" in competition -- found himself back in Southern California, seated with his teammates at a row of monitors on a high-tech stage, ready to do battle in the "League of Legends" college championship.
