A few years ago I got crucified by a female streamer for stating games is a majority male hobby. I then did a deep dive to see if it was, and Yes, gaming is majority male hobby.
Yes, women make-up half of gamers, if you include mobile and casual games. Take them out, its mostly men.
In short, Women aren't playing Call of Duty.
In fact, I'll go further, men are the primary audience for certain games genres like shooters. Trying to cater to women, who are not the primary audience, is one reason(of many) gaming is in a giant slump.
