From Xfire: “Hyping up a video game is normal. It’s the publisher’s job to handle the marketing and release of the game. The better they are at handling that end, the more likely they will recoup the money they invested towards the development of the game. Unfortunately, publishers tend to overdo their job, overselling the game so that it commands the audience’s attention to drive sales.”
