Punch-Out! is…well, Punch-Out! The story of the plucky underdog against the overly qualified (and humongous) champion continues to delight us all in popular culture. I dare say Punch-Out as a series came directly from the influence of Academy Award-winning film Rocky, who turned this simple tale into a part of our public consciousness. Video games do much the same, throwing overwhelming odds at the player only for them to rise above their circumstance and emerge triumphant.
So yes, it’s basically the book of Esther in video game form.
