For instance, people thought non gamers did not buy games until Myst. I think there are a lot of games out right now that women would like if made aware of them and given the opportunity to try them. Last Resort Designs. I can't speak for the whole company. As for me, I would if it made sense to the game, and did not appear arbitrary.
Fighting games have women, but they are still played mostly by males.
There are definitely a lot more males in the game industry, but I think this is because most of the people making games were game freaks before they started making games. Because most of the people playing games were male, you get in a catch 22. Everywhere I have worked would be more then happy to have more women on the teams. Now the industry is changing, many people are being hired out of school for their skills, and it's ability to make games, not play games that will get people hired. This is good for women, and non gamers.
