TF2 is now free on Steam

From what I know (i.e. very little) you have to buy something, the price doesn't matter. You still spend 5, because that is the minimum amount of cash you can add to your Steam wallet, but then you can go premium and skip the ads before every game and get new maps.

Oh wait, that is a different, far better, F2P game.

So, I spend 30p and get the same as people who paid 8 or even more for TF2?

Sweet.

According to the FAQ, yes.

But if you want to buy something from the item shop you have to spend 5.
