What games you got for FREE!

I'm just interested. I only bought Team Fortress 2 like 3-4 years ago from shop for real money...I WANT A CREDIT CARD!
Anyway here is my free games list:

1. Half Life 2: Deathmatch/Lost Coast, I have a Nvidia video card
2. Portal, It was free when the Portal 2 announcement trailer came
3. Garry's mod, Friend gave it to me cuz it was cheap and
   because he stole my orange box code...we didnt know it was a one use code. I was young :(
4. Portal 2, From the Steam Santa I found it in the first gift box and that was luck
5. Super MNC, Free beta keys but my pc is too weak for the game. At least steam let me make an account

And sorry for my bad English I'm from Hungary and I still learning the language.
