Gamasutra has a piece on Organizing and Formatting Game Dialogue. An interesting look at one of the often overlooked parts of game creation. From the article: "Here's the deal: two weeks before your game hits beta, the lead designer on your project adds some new functionality to the game. In addition, some of the pre-rendered cinematics are changed. Nothing major, just a few cuts and additions here and there. All this requires you, the writer, to create some new dialogue for various characters in the game, including the protagonist, some of the bad guys, and some allies."
