Just play the Cadillac of MMO's. You can make characters on a PvE realm so she doesn't have to worry about fighting so much, and it's HUGE. So much character customization, some pretty neat mounts, tons of mini games, super cute pets, it really is a beautiful world. Also, it's the only game I can think of where women are actually welcome. I don't play it anymore, but my wife is running around in Goldshire as I type this.
