Yeah, I haven't been on in a while, ever since this damn update for TF2 came out.
It allowed players to buy hats (at ridiculous prices) and other random items with real money.
It also brought in a bunch of new class weapons and hats, and finally allowed trading.
I had 2 hats before the update came out, now I have over 30, shit is crazy.
