Ever since I ponied up the cash for a Gold Live membership, I have been contemplating giving Team Fortress 2 a spin, since The Orange Box was already sitting on my game shelf. However, the mission-oriented gameplay, combined with the fact that the game is well over a year old, have me worried that I would end up entering a realm of long-practiced strategies and techniques and facing a steep learning curve. Is this a valid concern, or should I be able to jump into a match (albeit as a newbie who will most likely spend a good while getting shot up)?
