I backed this Kickstarter project last year, and by doing so I'm (unofficially) contractually bound to support Anita Sarkeesian in her effort to educate the masses about true feminism and the role of women in video games. I bet you never guessed I'd be a feminist eh? (Also men can be feminists, look it up.) Well guess what, women are awesome, and we still treat them pretty badly. So if you want to see an interesting and enlightening video please watch this.
Also, check out their tumblr of games where the Damsel in Distress trope is used.
