This book a call for all amateurs creators around the world to use videogames as means for their personal expression. The authors states that most commercial videogames are guided by market analysis more than creativity, as she concludes that this trend results in locking the expressive potential of videogames. But for Anna Anthropy, an American game designer recognized for its unique creations, there is still some hope left: what the industry can't or don't want to produce, the amateur game designers can. So she calls out any person, and more specifically anyone who doesn't match the "game industry worker" stereotype, to try making games in order to help the whole medium evolve.
