Roberts and Isbell (2008) define a drama manager as a coordinator that tracks narrative progress and directs objects and agents toward a narrative or training goal. They say every approach rests on four parts: plot points (with precedence constraints), drama-manager actions, a model of player responses to those actions, and a model of authorial intent. They list ten desiderata (speed, coordination, replayability, authorial control, player autonomy, ease of authoring, adaptability, soundness, invisibility, measurability) and say some conflict, notably player autonomy and authorial control. The analysis is qualitative and, by the authors' own statement, speculative about what authors can actually exploit.

Curator qualifications: Section 2 lists ten bulleted desiderata: Speed, Coordination, Replayability, Authorial Control, Player Autonomy, Ease of Authoring, Adaptability, Soundness, Invisibility, Measurabilty [sic]; 'some of these desiderata are in conflict. For example, player autonomy and authorial control are known to be in tension'; 'no one of the desideratum is more important than any other'. Choices motivated by building systems, surveyed authors' motivations, and discussions with researchers. Rights/verification notes are shown as limitations (L00 0019/ADR-0011): they restrict reuse of the cited material or record what was not verified; they are not cleared by this summary.

Limitations: [ambiguous] No scoring thresholds in the source (producer synthesis correctly labelled).

Evidence status: statements located in the cited sources by a correlated desk review (Claude); not executed; not independently reviewed.
