Overview of what "Sexualized" Women Are
Games are often marketed to the male 18-34 demographic, meaning that it often behooves developers to include sexualized female characters. Some games are marketed with this aspect as a prime selling point. An example of this is the recent Ninja Gaiden Sigma 2 commercial focusing on the breast jiggling mini-game when the core game is about being a ninja. Once games made the leap to 3D, it became easier for games to render implausibly busty females (a far cry from pixel art bikini Samus). 3D women like Lara Croft began appearing, who dressed in tight shirts and shorts to emphasize her figure. The Dead or Alive series took off primarily on the promise of its alluring female character models.
The outfits that these characters wear are usually ridiculous and seem unfit for the task at hand.
Bayonetta is a recent example of an extremely sexualized female protagonist. Her sexuality is linked to gameplay: some of her attacks cause her clothes, which are made of her hair, to fly off, revealing more and more of her uber-endowed figure.
Examples of Sexualized Women in Gaming
Lara Croft Franchise
Lara Croft Series. Throughout many of Lara's games, Lara is seen usually strip teasing her body. Just zipping down a skin tight spy suit, and just revealing just a little bit of her body. While not showing her fully naked, however just showing her cleavage and her sexy body (especially her legs). Many times she does this to go undercover, or she is just changing her clothes. She's also seen in a revealing dress, and with a wetsuit that just covers her body, and not her legs. So looking at Lara Croft, she is one of the most famous sexualized woman in gaming history.
Fatal Fury/King Of Fighters
Fatal Fury sex star, Mai Shiranui is probably the most sexualized woman in gaming. Even in the beginning years of fighting games, Mai was still a sexy character to use. Usually players would be this character to see her huge breast bounce up-and-down, or see her underwear when she would kick. These were really crude examples of what Mai's character was like. After winning a fight in the game, Mai's breast would bounce and she would laugh at seeing this. Currently, she is still like this, however with more sexualized content. She is currently in the King Of Fighters XIII game.
Mass Effect 2
In Mass Effect 2, players can be a male or a female character named Commander Shepard (the first name is up to the players). When being a male character, players will partake in having a relationship with many women in the game. Aliens and humanistic women alike, Shepherd will have many chances to have a "working" relationship with more than five women. Commander Shepherd can usually have more than two girlfriends at a time, but if the player makes a wrong move, a certain relationship that a player might want to keep can disappear. However, seeing many sexy hot women isn't all what Commander Shepard can do.
At different points in the game, Shepard will be in the bed, find a closed room, or some other area where he can have sex with the character. While not revealing anything and just keeping the "M" rating with no naked bodies being seen, players will get a glimpse at Miranda Lawson with no battle suit on which makes most players drool. Most female love interests have a scene with Shepherd, but not everyone.
Mileena from the Mortal Kombat franchise has been one of the lesser known, sexualized woman. While everything about her looks incredibly sexy, her mouth is what throws players away from looking at her "most" revealing costume. There are many other characters in the Mortal Kombat Universe like, Sonya Blade and Kitana. Both are very famous and very hot sexualized women. Usually, their breasts will have exaggerated physics in the newer versions of Mortal Kombat. All the women in the Mortal Kombat franchise are known for their ridiculously revealing clothing and Mileena's alternate costume, which is awarded from completing the challenge tower, has been called the most revealing fighting game costume of all time.
Batman Arkham Asylum & Arkham City
Throughout Batman Arkham Asylum, Batman encounters many of his sexualized female rogues. There are only two characters that are main females in Batman's game. Batman battles both Harley Quinn and Poison Ivy, who both share a secret love interest of the Dark Knight. As you progress through the game, you see Poison Ivy's revealing skimpy underwear and also her half-buttoned-down shirt which reveals a breast peek. For Harley Quinn when Batman finally finishes Harley, he sees a piece of paper in her bra which is near her breast. In game (and shown), Batman takes the piece of paper that is in her bra and reads it. As shown, Batman puts his hand on Harley Quinn's breast instead of just taking the paper. In Arkham City, Catwoman is shown with a zipped suit that shows some of her breast, but not everything.
