revial: It's not just a simple matter of extracting a dialog file.
nondeplumage: I don't mean the programing script. I mean the flowcharts, the written on a word processor story script itself, notes, all that crazy good stuff that goes on before the start of making the game a game itself.
He doesn't mean the programming either. The thing is, a movie script is a linear story, while a game "script" is essentially the design documents for a game. First of all, they're not particularly readable to anyone but the developers working on the game. Secondly, they're not likely to be kept up to date as development progresses and the deadline approaches. Thirdly, that kind of document is internal to the developer, and is unlikely to be shared with the general public ever.
