Bestselling books don’t usually begin life as video games. Yet some gaming franchises became so popular that publishers realized players wanted more stories, more characters, and more time inside their favorite worlds. What followed was a wave of novels that expanded beloved universes, filled in missing chapters, and in some cases became major successes in their own right. These are the video game franchises that proved great stories aren’t limited to a screen.
