Well, I have had pleasant and unpleasant experiences with "both sides of the coin" gaming and nongaming women.
Perhaps the worst situation was the girl who pretended to like gaming until she decided it was time for me to "grow up" and out of gaming ... after she married me.
Ironicaly, years after she said, "Now, you know that in the real world people won't be playing these games." I keep finding lots of people who have, or at least give gamers the benefit of the doubt. On the other hand, I work in a office, so I keep my gaming to myself so as not to be judged.
I have my best results with women who had interests
similar to gaming. People who like fantasy/SF/horror fiction or movies. I am also a writer by trade, and there are women who like a creative guy, the more creative the more "intellegent and exotic."
My suggestion:
You should, however, expand your definition of "gaming stuff." Get out and join some book or poetry clubs.
I have also heard that places like Barnes and Noble and Borders have become discretee weekend pick-up places for people with an intellectual bent. While I haven't personal verified this, I took a date to such a store on the weekend and it was amazing how many women were dressed to the nines just to find a book. I also suggest that you don't overlook "mundane" women for the sake of a "perfect gaming girl." It is possible to arrange a comprimise where your gaming is basicly "guy time." Most good women realize this let it go. The women who have a problem with such a concept would have similar problems with football and such.
