Better believe it. Games are big business. “Video game sales surpassed movie sales last year, with a staggering $9.4 billion take. Mario, the plucky plumber and star of an 18-year-old series of games, has brought in twice as much revenue as all five Star Wars films combined. The Sims, a digital family whom players manipulate through every stage of life, has sold nearly 20 million units. So it’s no surprise that book publishers are turning to video game novels. Yes, novels.”
