I'm a girl and I HATE the sims. (I hate pink too) UT3 and COD4 are the only games I play. I play at least 4 hours a day. I have been playing shooters for almost 10 years.
Never a good idea to generalize. 
It's never a good idea to stereotype. Generalizing is not only natural, it's necessary. I prefer shooters as well, but let's not pretend we're anything other than a minority. Generally, there are some things that appeal to one sex or the other, and some things that appeal to both. I like watching football, but generally, this does not mean both sexes do. Contrarily, I don't care for most chick flicks, but that doesn't mean they aren't chick flicks.
A lot more women are gaming now than 5 or 10 years ago, but it's still a male dominated(ratio-wise) hobby. I am happy when games like Spore come out. Borrowing from marijuana prevention vernacular, they're gateway games

Despite being such a huge influence in my daughters life, she's never shown much interest in gaming. But when something like the Spore Creature Creator comes along, it at least gets her on the computer playing something. Slowly but surely, with the help of Will Wright, I will make her a gamer.
Tribes 2 was the awesome, but Tribes was still and the greatest ever.
I never cared for Tribes 2. Tribes remains one of my favorite games of all time.
