I know two girl-gamers in real life... one is a verrrry casual gamer, but she still would class herself as a gamer I think, she plays her brothers' FPS games, like SWAT 4 and Fear... the OTHER gamer girl I know will only play turn based RPG's, lol, and she has a really awful computer, and no consoles, so she can't play anything made after about 2002 xD She plays Neverwinter Nights at about three frames per second...
But as for what I think about girl gamers, I really don't find it appealing at all... I spend so much time with games, and having a girl that wouldn't know the first thing about games would be such a good thing... I mean, games, to me, have always been somewhat of an escape from reality, and having a girl that's as into games as I am... well, that would defeat the purpose of having a girlfriend, as I'd be doing just the usual things... I'd want to get out and do some real things with her.
