Essentially, what is the primal action(s) that resounds most strongly with women?

We know that for men it is fighting, and gaining power (see video games- the most popular ones have some sort of combat and/or levelling system implemented). It's what attracts so many boys and why video game nerds are almost exclusively male.

What is the female equivalent of this type of primal desires/needs? Can't be video game style violence or we'd have a lot more female needs (read: female nerds, not attention seeking 'girl gamers'). So what is their equivalent?
