There isn’t a certain genre.
First female friend of mine plays Shooters, Sims, City Simulations, Strategy Games.
Second one plays Assassins Creed, Zelda and such games.
Third one plays League of Legends, Borderlands, some MMOs.
Fourth one plays Assassins Creed, Far Cry 4, Evolve, Left 4 Dead.
They couldn’t differ more from each other. 
Also we don’t have much girls here in the UE4 community. Better make a game YOU like than making a game others like.
