Game Makers Aren't Chasing Women
Thanks to Wired News for their article discussing what videogames women are playing, and whether the mainstream games industry is serving them well. According to the piece, "Observers say the industry isn't exactly rushing to make PC and console games that appeal to both men and women, let alone women alone. That's despite the massive success of games with crossover appeal, such as The Sims." However, a researcher on the subject suggests being too calculating doesn't work either: "Making games in which you get women to do 'women things' isn't a very successful strategy." So what does?
I'm in my mid-twenties, and my girlfriend plays (some) video games, and that's fairly unusual.
My sister, who's 17, plays video games and that's true for at least half of her age group.
My 8-year-old female cousin loves video games, and doesn't have any problem with them at all. Just as video games grew into the mainstream for males, they are moving that way with females (although more slowly).
Playing video games doesn't have to be a "masculine" or "feminine" activity any more than watching a movie. There are plenty of games that can or could appeal to any gender.
That being said, I think video games lost a lot of girls when they started having more than one button. They lost even more when they went to 3D. When games got to the point that you had to read instructions or do tutorials, the gender gap emerged. The arcades also declined sharply at that point.
