Team Fortress 2I've recently played this game for a bit, mainly because of their awesome "Meet the X" trailers, which were really cool. The game itself seem's really well balanced game wise, but personally feel this balance is not for new players. I had a few extra steam credits so I bought a weapon from the game (since it's free to play, they make revenue from in game purchases).
After buying the weapon, I found my performance greatly improved. This kinda put me off the game. The fact that some one paying money get's an advantage over the normal player. But hey, it's free to play, so what can I say.
Overall, great game If your into PC gaming (personally I'm not) but it's still really fun. The team aspect not as good as Battlefields though.
To describe it in a small phrase: "Call of Duty made good, then given a shit ton of crack"
