'Tokyo, Japan (CNN) -- The game begins with a teenage girl on a subway platform. She notices you are looking at her and asks, "Can I help you with something?"

It is little wonder that the game, titled RapeLay, sparked international outrage from women's groups. Taina Bien-Aime helped yank the game off store shelves worldwide.

"This was a game that had absolutely no place on the market," said Taina Bien-Aime of women's rights organization Equality Now which has campaigned for the game to be taken off the shelves.

"It's obviously very difficult to curtail activity on the Internet. But the governments do have a role in trying to regulate this sort of extreme pornography of children, both in their countries, and through the Internet ," she said, adding that they were calling for the Japanese government "to ban all games that promote and simulate sexual violence, sexual torture, stalking and rape against women and girls. And there are plenty of games like that. "

A member of the Institute of Contents Culture, who did not want to give CNN his name, said restricting game themes limits freedom of expression.

"In my opinion, RapeLay's storyline went too far. However, if a game creator wants to express something and create content out of it, a government or public entity shouldn't have the power to restrain it."'

Video games depicting violence against men also exist, but of course there is no outcry against those games. There is only a move to ban games that involve sexual violence against women. Why is that?
