    Temporal coherence: if plot requires two characters to fall in love, their birthdates must be within a reasonable range of one another

  41. 41 Classification Scheme

  42. Plot Automation 42 Manual Structure Template Constrained Automated

  43. Plot Automation 43 Structure Computer provides plot structure, but no

    specific events or event orderings. e.g. Scrivener
  44. Plot Automation 44 Template Computer provides plot template with events

    in order, but instantiation with existents is left to the human author. e.g. Propp grammars
  45. Plot Automation 45 Constrained Author provides initial state or other

    narrative constraints; computer gives complete plot populated with existents. e.g. GME, Mexica, Prom Week
  46. Space Automation 46 Manual Modification Simulation Constrained Automated

  47. Space Automation 47 Modification Author provides a starting point, but

    the computer can modify it, e.g. to suit the plot structure. e.g.: initial state revision; late commitment
  48. Space Automation 48 Simulation New spatial content is generated by

    simulating interactions between hand-authored existents, resulting in an initial state for story. e.g.: Universe’s family tree generation
  49. Space Automation 49 Constrained New spatial content is generated to

    satisfy authored constraints. e.g.: Dwarf Fortress
