Agents
Game elements that can be interpreted as having goals.
Games can be viewed as simulations, i.e. an imitation of some aspect of reality. While these may overlook other aspects and include fantastical elements, games often include representations of Agents that actively work towards goals through manipulating the game environment. These Agents may be the points through which player can interact with the game or be the conduits for game facilitators or separated sets of rules to enact other inhabitants in the game world.

Examples
While the ghosts of Pac-Man and the alien of Space Invaders can kill the player they do not actively react to what the player does[1][2]. In this they show little evidence for agency. In contrast, the enemies in later games such as the Doom series, the Fallout series, and the Left 4 Dead series adjust their actions in response to player actions. This is typically enhanced by them going from passive modes to active modes when first detecting the players.
Players' characters in roleplaying games such as Dungeons & Dragons and GURPS are examples of Agents since enacting or saying what the characters do is the way they can affect the game world. Likewise, all the non-player characters and monster controlled by game masters are Agents.
The computer programs underlying Façade and ELIZA give rise to characters that can be experienced as having personal goals and emotional states, and exploring these is the prime intention of the designs.
Using the pattern
The presence of humans controlling Avatars or Units in games makes it nearly impossible to avoid have Agents in games, and one could argue that unless human-controlled Agents exist in the design it is not a game. The description of Crobots, P-Robots, etc., as games show that others argue that this is not necessary.
Avatars, Characters and Units are examples of how Agents can be created by being directed by humans (or only seem to be so due to actually being Mules or AI Players). Enemies, NPCs and Units controlled by Algorithmic Agents or Game Masters are examples of other common types of Agents.
Agents as a pattern are often volatile, that is players tend to rationalize them to simpler mental constructs if possible (typically Converters, Containers, Obstacles, Self-Service Kiosks or Traps)[3]. This in practice means that they are perceived as game elements which move and act with Predictable Consequences and where one doesn't have to assume they have intentional goals. The use of Game Masters, and for Multiplayer Games other players, can make it impossible to reduce Agents behavior to a set of rules since the people controlling them can have an Unpredictable Behavior, at least as long as the Game Masters and players aren't simply following a set of rules (they may not have an option unless the game has a Freedom of Choice or Randomness). For Agents built on Algorithmic Agents giving them Unpredictable Behavior is somewhat of a paradox since they are a set of rules fundamentally but several tricks exists, including Own Agenda, Ambiguous Responses, and Randomness.
