I played TF2 once.. At Geek.Kon's LAN room earlier this year. I actually didn't like it... Not a wide character selection, and it lost my interest after a few rounds. Im all for WoW, Wc3, and UT2k4, but TF2 was not for me.
I did however enjoy the medic guy. He was fun. Unless you got stuck alone. Then you got boned.

<offtopic> Also, Derek, I have a gamer girlfriend too. And I'm friends with plenty of other girls that game. Some of which I actually considered dating, before I was going out with Megan. -cough cough- And she even has a gamer name, in real life. (Kirby) Luls. <3 </offtopic>
