Here is the full Review for TF2. (lol that rymed)
A fun game even though it is quite old, anyway I am not saying it has bad gameplay I am only saying the Graphics are a bit old. But that won't stop me from playing yet another great valve game. Especially in the competitive part of the game, I would not want super detailed maps or weapons that will distract me I just want great gameplay.
So for all those that just want a beautiful game, this may not be your game. But for all of those competitive gamers go ahead and get rumbling!
