My first girl-friend threatened to leave me in case I bought a game boy. It's not just stereotypes from the media, it's also an experience that lots of men have made in their lives. But that doesn't mean we don't like the idea of women playing games. Quite the opposite. I still remember the first time I saw a woman wearing an Atari T-Shirt. I could hardly believe my eyes... Turns out by then Atari didn't really exist anymore and was being rebranded by whoever bought the Trademark, but still (I was attracted, but I didn't talk to her, so no further story to that).
It's just that it feels like a waste of time trying to get women interested in games. If they want to play, fine, but why try to make them? (Speaking from the consumer perspective - game makers of course have different incentives).
Next week I plan to have a C64 revival party. I will invite women, curious to see how many of them will also play...
My advice for women interested in computer games: just do it/try it. Don't waste time wondering if you are allowed to do it.
