Game Studio
Narrative games, and the visual novel first.
Narrative games, and the visual novel first because it is the smallest thing that is really one: a script, a cast of references, branching, and a build. The part nothing here models is state — every other kind assembles one fixed timeline, and a player carries a different one through each run.
This Studio is planned, not built. It is here so the shape is visible
and can be argued with before it exists.
The workflow
Four phases, and only the stages this kind of production actually has —
a commercial has no bible, and showing one would make the tool read as television
software to everybody who is not making television.
