I played occassionally with my younger sister when we were kids so she probably won a few rounds. But with online gaming, probably when I started playing Left 4 Dead, that's the first online game I played with female players I was aware of (I'm more inclined to wear my headset with that game). I noticed that women don't seem to have the same built-in Rambo impulses as many careless male players, they usually made for worthy opponents or team mates.
