CVG, Kutaragi insisted on the use of the font, and it was one of the first design elements chosen for the console.
According to Sony's Teiyu Goto, "If you really look at the PS3 contour carefully, it is rounded when viewing the console in profile. Rather than creating a typography with all the risks that entails, it was wiser to use the one from Spider-Man, for which Sony has the rights."
Er, call us confused, but what are all the risks that creating a new font entails? Death and destruction raining down? Sharp edges? Cats and dogs living together? Thankfully, Kutaragi wasn't a hardcore Comic Sans fan, or who knows what the PS3 would have ended up looking like.
