AI Agents in Video Games: They Have Been Here a Long Time
Every video game character that does stuff on its own is sort of an agent. The bad guy that chases you. The teammate that helps. They are all agents.

The big idea
Video games have had AI agents for decades. Every character that is not controlled by a human — the bad guy, the helper, the shopkeeper — is an agent making decisions.
Some examples
A goomba in Mario walks back and forth. Simple agent.
A creeper in Minecraft chases you and blows up. Trickier agent.
Your AI teammate in a shooter game decides where to run, who to shoot, and when to heal. Smart agent.
The villagers in The Sims live their whole pretend lives as agents.
Try it!
Pick your favorite video game. Try to spot 3 characters that are agents (controlled by the game, not by a player). Watch what they do — can you figure out their rules?

A character in a video game walks back and forth on a small platform, turning around when it reaches the edge. What type of character is this?
A character that can think and feel like a human
A player-controlled character that responds to button presses
A real person acting in a movie about video games
An AI agent that follows pre-programmed movement rules
Why is a Goomba from Super Mario considered a 'simple' AI agent?
It was created using advanced machine learning
It can walk, jump, and collect coins on its own
It makes decisions about story plots in the game
It only follows one very basic rule — walk forward until hitting something
An AI teammate in a shooter video game decides where to run, which enemy to shoot, and when to use health packs. What makes this agent 'smarter' than a Goomba?
It was added to the game in 1985
The AI teammate is controlled by another human player
It is alive and actually thinks about its choices
It can consider multiple factors at once to make decisions
Why are AI agents in video games not considered 'alive'?
They only follow rules that programmers wrote — they cannot think or feel
They only exist on older game consoles
They are controlled by ghosts
They are actually human actors in costume
A Minecraft Creeper sees a player, moves toward them, and then explodes. What is happening inside the game?
The game is broken and behaving randomly
The Creeper is dreaming about the player
The Creeper's programming tells it to chase and explode when a player is close
The Creeper is being controlled by another player nearby
In The Sims, virtual villagers wake up, go to work, come home, and watch TV — all without the player telling them what to do. What best describes these villagers?
They are not actually in the game
They are recordings of real people's daily routines
They are controlled by other human players online
They are AI agents living their own pretend lives based on rules
What would happen if a video game had absolutely no AI agents at all?
Nothing would change — agents don't affect gameplay
The game would automatically win by itself
Every character would have to be controlled by a real human player
The game would be more exciting and fun
A shopkeeper in a fantasy video game offers to sell the player weapons. The shopkeeper stands in one spot and says the same lines every time. Why does the shopkeeper act this way?
The shopkeeper is controlled by the game's story director
The shopkeeper is shy and doesn't like to move
The game console is not working properly
The programmer wrote rules that make the shopkeeper stay put and say fixed lines
You watch an enemy character in a game always attack when you get within a certain distance, but never attack from farther away. What can you conclude?
The game is broken
The character is guessing randomly whether to attack
You have figured out one of the character's programming rules
The character is choosing to be nice from far away
What do all AI agents in video games have in common, regardless of how smart or simple they are?
They all make decisions based on rules a programmer wrote
They are all alive and can think for themselves
They all look like robots or aliens
They can learn and become smarter over time on their own
An AI agent in a racing game slows down when it nears a sharp turn and speeds up on straight paths. Why does it behave this way?
The programmer wrote rules telling the agent to slow down near turns
The game wants the player to feel sorry for the AI
The agent is tired and needs to rest
The agent is showing off to the player
Why do video game developers create AI agents instead of just recording animations for every action?
Recorded animations take up too much storage space
Animations are too expensive to create
AI agents are required by law
AI agents can react to what the player does in the moment, making games more dynamic
A player notices that a ghost enemy in a game always takes the shortest path through the maze to reach them. What is the most likely explanation?
The game is cheating
The ghost's programming includes pathfinding rules
The ghost is actually a real person playing the game
The ghost is telepathically reading the player's mind
What would be a sign that an AI agent's rules are 'clever'?
The agent sometimes makes mistakes on purpose to be nice
The agent does exactly the same thing no matter what the player does
The agent refuses to follow any rules
The agent can do surprising things within the game's rules that players didn't expect
You want to find AI agents in your favorite video game. What should you look for?
Characters that do things without you controlling them
Characters that are exactly the same as your player character
Characters that only appear when you press buttons
