Who Introduced You To The Game?
Men and women tend to be introduced to the game in very different ways. Men are more likely to have found the game by themselves or through a friend, whereas women are more likely to have found the game through their romantic partners or a family member.
The difference in being introduced by a romantic partner is quite striking (27% vs. 1%) and may in part explain why female gamers tend to be older than male gamers. Given that people with stable romantic partners tend to be older, the age difference may be driven by this difference in how men and women are introduced to the game. This also goes along with the finding that female gamers tend to play with a romantic partner.
