You should be able to find a lot of indie dev games on Steam for the PC; games which would appeal to both males and females. There are a lot of good indie games out there, too. And they are cheap.
Do you play Nintendo games? You have a great backlog of Nintendo games to check out if you've missed a lot of their great hits. Also, if you have a PS3, have you played Journey? A lot of people call it one of the best PS3 games (it is an indie game that released on PSN).
