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.

5 min · Reviewed 2026

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?

Practice this safely

Try this with a low-stakes example and a trusted adult nearby. The goal is to notice how AI talks about game AI, not to let it make the decision for you.

Ask AI to explain game AI in plain language, then underline anything that sounds uncertain or too broad.
Give it one detail from "AI Agents in Video Games: They Have Been Here a Long Time" and ask for two possible next steps plus one reason each step might be wrong.
Check NPC against a trusted source, teacher, adult, expert, or original document before you use it.
