Girl gamers get a lot of ****, but a large majority are really good. Back in the days of halo 2 I used to play with quite a few outstanding girl gamers who played just as good as us lot. Nowadays I don't catch many online, I see the odd girly name but that's usually in pre game lobbys so don't pay much attention in game as to how well there doing. What ****es me off is nerdy guys who suck up to girls on the internet, without naming names I've noticed it going on everywhere, especially on xbox live. You get these idiotic girls who make sure everyone knows there a girl and suddenly hordes of nerd jump to them, like if you play a game with them in free fall modes for instance they will protect the girl and gang up on the one guy (usually me) who doesn't fall into the idea that all girl gamers need special treatment. I've seen that done so that's not just me making an example up.
Them kind of girl gamers don't belong on xbox live and before I get flamed by the ladies I'm not saying that description fits you all. Like I already said I've seen expert girl gamers, its just that handful that believe there unique on a largely male dominated online system.
