Stuck in a dungeon in a video game? Is there a boss with no discernable weakness? Can't find a specific item to complete a sidequest or to craft that special armor? Decades ago, players would have to rely on flipping through the pages of a guidebook that may or may not give them the information they need. And even if they did, those guides offered minimal story information and no warnings about bugs or glitches. As soon as a game receives an update, that guidebook likely becomes obsolete.
