To celebrate the 25th Anniversary of the release of Half-Life we reunited the original development team to share their memories of creating Valve's first game.

To celebrate the 20th Anniversary of the release of Half-Life 2, we've gotten members of the HL2 team back to talk about the game's development, how we almost ran out of money, what it was like when we were hacked, what happened when we were sued by our publisher, the birthplace of Steam, and much more.
