Once upon a time...

      Someone had to write the story for every single character in a game.

People still do it!

Time to create a Massive Artificial Drama Engine

Our path:

Represent characters by behavioral probabilities and optimize them by the presence and abundance of archetypes

Let the critters lead real lifes

Let's welcome our rat overlords

Create random worlds populated by rats.

Every rat is a finite state automaton

Probabilites are defined by profiles.

The environment they live in is scored by emerged archetypes

Testing 3 different scenarios

Territorial war, revenge and Shakespeare

Key parameter: number of profiles

Archetypes are identified in world logs via regexes

Archetype match adds to fitness

But stories emerge!

Interesting stories emerge in worlds evolved via archetype matching.

Fleshing them out is a different matter.
