TF2 Thread, now featuring HALLOWEEN!

I'd feel like a complete idiot not knowing how to play the diff classes, mostly.

Why should that stop you from playing? I have no idea how to play any of the classes except from the random readings I do every now and then, and basing their playstyle on their weapons and stats. Heck, I immediately jumped onto Online play the moment I finished up downloading the game and played the Medic. I had no idea what button does what, I nearly failed to Ubercharge my first time because I didn't know Mouse2 activates it. Yet, I won my first three games. It's not that bad as long as you don't hop into a game or server that consists of nothing but professional players. Whatever common sense experience you picked up from previous FPS games can be applied here as well. Just have fun learning!
