What was your first steam game?

Fallout New Vegas

Portal. Got the disk as a gift from a friend :)
Then... Maybe Broken Sword Trilogy?

Portal. I created my Steam account during a promotion they were giving away Portal. I had already played and beaten the game on Xbox 360 at that point.

Lord of the rings: War in the north .... pretty hell of a way to start the steam journey :P

The Orange Box. 2 years ago on this account. On my old account (5 years) Counter-Strike 1 Anthology.

A retail copy of the ship

The Orange Box.

Registered in 2008, I had only ATI promo. Then in 2011 I got Terraria.
