In general, though, it's easiest to think of Attributes as numbers that change during the course of the story. The following are the 13 Erasmatron Personality Attributes. As the storyworld builder, you name the actors you create as you would name your children. Name is an attribute that does not change throughout a storyworld's time of play. Gender - Gender is simply the attribute determining whether an actor is male or female.
Gender is an attribute that also never changes throughout the play of a storyworld.
Thus, the verb SexChange can't work in the Erasmatron. The designer, Chris Crawford, apologizes to those who take offense at the suggestion that women are genderless creatures. During the time that an actor is occupied, the storyengine will not permit that actor to do anything else. The storyengine simply takes the current time and adds the ExecutionTime of the verb, and stores the result into the OccupiedUntil attributes for both the Subject and the DirObject. Only the storyengine gets to change it.
