TF2 has to be present in every true gamer's Steam library. Seriously. Your library cannot be complete without this amazing FPS. You know, it may not look that neat from the outside to some of you, but trust me. It is. You can spend like, your whole weekend on it, and still not quench your thirst for TF2. I'm going to stop here, because I can't really say much more. This glorious game is... Indescribable.
