"Minecraft" and "Dwarf Fortress" also have emergent narrative features due to the abstraction of how elements are represented in game, allowing system-wide features to apply across multiple objects without the need to develop specialized assets for each different state; this can create more realistic behavior for non-player controlled entities that aid in the emergent narrative. For example, in "Dwarf Fortress", any of the living creatures in the game could gain the state of being intoxicated from alcohol, creating random behavior in their movement from the intoxication but not requiring them to display anything uniquely different, in contrast to a more representational game that would need new assets and models for a drunk creature. Because these are abstract and interacting systems, this can then create emergent behavior the developers had never anticipated.
