Lack of Nudity in Video Games

From Loot Ninja:

"I have to tell you that there is an utter and constant lack of nudity in video games. Why can't I play a mature rated game and see some gratuitous breasts walk by? The first major game to incorporate any kind of mature content was God of War with the mini game where you had sex and got extra Red orbs. GTA tried to have it incorporated into their games, but was reduced to calling a hooker over to your car and driving to a shaded area where the car just jumped up and down."
