What's the first steam game you ever played? How long ago?

Half-Life 2 back in December 2004. Man that was a long time ago....

Counter-Strike, probably ~9-10 years ago. And god was I PISSSSSSED when they added Steam to it. Now I can't live without Steam. Funny how things change.

Long, long ago... In a galaxy far, far away...a young boy took his best friend's Counterstrike copy and registered it accidentally. He honed his FPS skills like no tomorrow to conquer the evil bots. Some may say he is still gaming today...

Counter Strike 1.6

Team Fortress 2 I believe. But I played Counter Strike 1.6/CZ/Source without Steam prior to that.

dark messiah of might and magic on its release date. absolute awesome game

Skyrim

portal, almost 4 years ago

Arma 2. That was the first game i bought and it was for DayZ. Then i started buying and playing a lot of games on Steam :D !

Team Fortress 2.. original f2p nab here 8)

TF2 I think

Warhammer 40k Space Marine, about a year or so ago

Modern Warfare 2, end of 2009 I believe. Didn't know about steam back then.
