The role of women in video games has been changing, and it will likely continue to change in the future. This involves both females who enjoy the hobby and how the fairer sex is portrayed in the interactive entertainment industry.
If you're interested in the subject, you might want to check out a new YouTube series from feministfrequency that takes an in-depth look at the history of female roles in games. The first episode is called "Damsel in Distress" and Part 1 focuses on the concept in question. Of course, it isn't new and dates back thousands of years, as cited in the video (Perseus saving Andromeda being one of the first examples).
There's no doubt that as social norms and perspectives change, our entertainment alters to reflect those changes. How women are depicted in games has always come under much scrutiny, especially during the days when Lara Croft was nothing but a sex symbol and most all women were…well, oddly and unrealistically built. But things do appear to be changing for the better, and speaking of Lara there's no better evidence of this than the recent Tomb Raider reboot.
Keep an eye out for future episodes if you find this informative.
