I've been experimenting with several different script formats recently and am not really sold on most of them. I figured while I'm at it I might as well see what you guys usually do. If someone posts one that really works for me it would be a big help.

When I'm actually writing NPC dialogue or other text that will appear as-is in the game, I assign each piece (meaning that the game will deliver it to the player as one chunk) an alphanumeric ID number. If it's an interactive dialogue or story I have the pieces arranged into a flowchart in addition to the basic linear format. Depending on the game and the development model (what you content you plan to make first vs. last), it might make more sense to categorize the linear part by:

- NPC (or by item for flavor text, and by object for text that appears on signs, pieces of paper, or computer screens within the game)

- Location within the game

- Time period within the game world/plot

- Quest line.

Then you can use hyperlinks or whatever to link those collections of dialogue pieces into their relevant places in the game design document if you want.
