Assigning secondary roles and sexualising female characters in video games have reduced since 2007, say scientists who examined over 500 video games from 1983 to 2014.
The researchers from Indiana University in the US analysed in-game recordings and database information of 571 different games with playable female characters.
They coded for five variables: genre, ratings level, critical score, release year and primary character, and then assigned scores for 11 character variables that examined the sexualisation of the character.
The researchers found that sexualisation of female characters peaked in the 1990s and have diminished since 2007.
The availability of primary playable female characters peaked from 1983-1990, and has since levelled off from a dip from 1991-1998, and they observed the same amount of sexualisation in Teen and Mature games, despite Mature games being designated for adults.
Past studies have looked at female characters on box covers and advertisements or limited to top selling games.
This is the first study to take a comprehensive look at female characters from actual game play and over such a long period of time.
"This study provides a long view of how trends in character design have changed over time, and assembles an otherwise disjointed picture of what has been going on with female video game characters over the years," said Teresa Lynch, from Indiana University.
The findings were published in the Journal of Communication.
