Why do some games only show half a face as their box art? Perhaps it's a sense of power or mystery. Either way, it makes for captivating boxart.
In the early days of gaming, box art was rather important. Gamers did not meet and discuss games over the internet back then, and the medium was not yet used to advertise games. As such, if a customer entered a store and saw a game that he did not know, the only thing he had to go on was how the cartridge looked.
These days, the industry has grown quite a bit, and the internet has become its main way of promoting games, through official websites, and through sites such as www.giantbomb.com. Consequently, most gamers already know more about a game when they walk into a store than the look of its packaging tells them.
However, that hasn't--and shouldn't--detain artists from producing good-looking box art that does the game contained within justice. A technique that inevitably draws attention to the box is putting a face on there that looks mysterious, and then cutting that face in half. Sometimes, even more than half of the face is cut off, leaving nothing more than an eye or a mouth. Spyro: Enter the Dragonfly's box art is a good example of this.
