Cutter XXIII said:The first of them was a great player. She really got into the character she'd created, came up with an appropriate background, read the rules often, role-played entertainingly, and generally added a hell of a lot to the group. I considered her a good friend, too, and the group would go out to play pool, drink some beers, what-have-you. Eventually I figured out that this woman had a thing for me, and was telling other players behind my back that I was making a huge mistake getting married to my fiancee. EXTREMELY awkward. When she moved away, there was great relief (on my part, especially).
I have had experience of friction between my wife and a single female player in my group. As a GM I think it's something you need to be aware of, that it can happen. And the GM (or whoever wears the pants in your game group - I even hear some groups are democracies, pshaw!

But assuming _all_ female players are going to be disruptive or cause problems seems like a very bad idea to me. It would be like me assuming all (eg) English or New Zealander players were no good because I'd met 1 or 2 I didn't get on with.
