This video game portrays not only etreme sexism, but is centered around violence towards women. In the game, you are encouraged to abduct women, and give them a "reassuring slap" if they protest. 

Furthermore, this video game only requires that you click a button saying you're 17 or older if you are playing online. There is graphic nudity, sex toys, etc, with only a single button to stop children from playing it.
