Games could potentially allow the player to play the game in a way that was not designed or implemented by the game developer, but that works nonetheless. Emergence in games occurs as the player is able to use the basic elements that are provided by the game developer to create new gameplay (e.g., stories or strategies).
Emergence in games is made possible by defining simple, global rules, behaviour, and properties for game objects and their interaction in the game world and with the player.
Emergent gameplay allows the game world to be more interactive and reactive, creating a wider range of possibilities for actions, strategies, and gameplay.
Local emergent gameplay occurs when a section of a game allows for new behaviour that does not have knock-on effects for the rest of the game.
Global emergent gameplay occurs when the simple low-level rules and properties of game objects interact to create new, high-level gameplay that alters how the game as a whole plays out.
