Obvious solution is obvious. Children need to be forced to play more Metroid.
American McGee's Alice
Resident Evil
Perfect Dark
Old NES Games based on the Alien movies (Ripley)
Donkey Kong Country 3 (Diddy Kong is the main character)
Chrono Trigger's main hero is a male, but 3 of the other 6 playables are strong females (2 of the others are a Frog and a Robot)
There are definitely more games with male protagonists than female, but there are enough to list.

Ironically, the first games I thought of, Fallout and Elder Scrolls, are probably not the best choice for a girl who can't read yet.
