Hmmm, just to point out something:

I do know there were females who played games on Atari and C64, especially interactive fiction like Zork and others. Or even games like Mario and Pacman. It seems some of them went on to play Adventure games while others, due to real life commitment like job/family/etc., stopped playing games.

What's really interesting is at least some of them have gone into casual games(hidden object games) including the latter group who decided to come back and play games again.

It's a shame humans love to innovate but then they sometimes leave the others behind.
