This post about female characters in video games from Jenn Frank is super-insightful. If you’ve played Portal, you’ll definitely remember the moment she references. And in fact, I think I’ll bump her argument up a bit and call it one of the greatest feminist moments in any medium in the last few years.
I was going to blockquote it, but it’s a) a mini-spoiler if you’ve never played the game, and b) a big chunk of her post—so just go read it.
Good comments, too!
