"If Half-Life 2 isn't viewed as the best PC game of all time, it's going to completely bum out most of the guys on this team." Well, $40,000,000 later, I hope it is the game to end all games. There's a story at GameSpot that is a VERY long read, but pretty much tells the story of the development of the new Half-Life 2 game, and why it took so long. It's very interesting. You can read it here.
