An archetype is used for creating new entities. It contains one or many
definitions for entities, along with relationship between them. It also
contains any extra data needed for a world simultion, such as thoughts
and knowledge.
Archetypes should be seen as blueprints for entity types, as they
describe how new one should be composed. They are created just as
regular entities, using the existing Create op functionality.
As an example, there should be one "human" entity type, with archetypes
such as "settler", "merchant", "soldier" etc. This differs from the
current setup where each of these are separate entity types.
It's currently a copy of the Mason ruleset.
Where Mason focuses on letting the users create the world themselves,
Deeds instead focuses on allowing world authors to set up enticing
worlds with gameplay and stories. In contrast to Mason there are more
features available to the world authors which allow for automatic
creation of entities and so on.
