9 Retro Games Where AI Was Ahead of Its Time


Ah, retro games—those nostalgic pixels that take us back to simpler times. But let’s not kid ourselves; those old-school games were anything but simple when it came to AI. In fact, some of those artificial brains were so ahead of their time that they’re still teaching lessons to modern-day game devs. Ready to embark on a blast-from-the-past journey into the world of revolutionary AI in retro games? Buckle up!


For a retro game to make it onto this rockstar list, it needs to meet the following criteria:

  • Innovation: Did the game bring something new to AI technology?
  • Complexity: How did the AI challenge or engage the player?
  • Legacy: Has the AI had a lasting impact on future games?
  • Surprise Factor: Did the AI do something so unexpected that it left your jaw on the floor?

Alright, let’s power up and warp to the past!

1. Pac-Man (1980)

Innovation: Pathfinding Algorithms
Complexity: Each ghost has its own strategy
Legacy: Influenced AI in maze-based games
Surprise Factor: Moderate

Remember the ghosts—Blinky, Pinky, Inky, and Clyde? Each had its own unique behavior and movement patterns. This gave Pac-Man an unpredictable gameplay experience that was pretty advanced for its time.

Did You Know?

The ghosts in Pac-Man were nicknamed “Shadow,” “Speedy,” “Bashful,” and “Pokey,” which subtly hinted at their individual AI behaviors.

2. Tetris (1984)

Innovation: Game Speed Adjustment
Complexity: Increased difficulty over time
Legacy: Set the standard for puzzle games
Surprise Factor: Low

Tetris not only kept track of your skill level but also adapted the game’s speed accordingly. That’s some rudimentary but effective adaptive learning!

3. SimCity (1989)

Innovation: Economic Simulations
Complexity: Handling variables like population, traffic, and economy
Legacy: Influenced the “Tycoon” genre
Surprise Factor: High

SimCity was ahead of its time with its complex economic algorithms, shaping a whole genre of simulation games.

Expert Opinions

Will Wright, the creator of SimCity, wanted to build a “software toy” that could simulate real-world systems. His vision has since shaped modern simulation games.

4. Metal Gear (1987)

Innovation: Stealth Mechanics
Complexity: Enemies react to sound and visuals
Legacy: Created the Stealth game genre

6. The Legend of Zelda: Ocarina of Time (1998)

Innovation: Context-sensitive Actions
Complexity: Varied NPC reactions
Legacy: Influenced 3D action-adventure games
Surprise Factor: High

This game had NPCs that not only followed daily routines but also responded to your actions in different ways. Plus, who could forget Navi, your AI companion, who would offer hints and strategies?

Did You Know?

Navi’s behavior was meticulously programmed to offer hints at just the right moments, making the game more accessible to newcomers without disrupting the experience for veterans.

Innovation: Coordinated AI
Complexity: Enemies work together
Legacy: Set a new bar for FPS games
Surprise Factor: High

Half-Life’s AI enemies would often work together to flank you, making combat both challenging and unpredictable.

Expert Opinions

8. StarCraft (1998)

Innovation: AI with Strategy
Complexity: Multiple tactical patterns
Legacy: Became a benchmark for RTS AI
Surprise Factor: High

StarCraft had AI that not only reacted to your moves but also employed varying strategies to beat you, making each skirmish feel like a high-stakes battle.

Did You Know?

The AI in StarCraft was so compelling that it’s still being studied in AI research to understand how it made complex decisions with limited resources.

9. Final Fantasy VII (1997)

Innovation: AI Scripting in Battles
Complexity: Adaptive enemy behavior
Legacy: Set a standard for RPGs
Surprise Factor: Moderate

Enemies in Final Fantasy VII would adapt their tactics based on your actions. If you used a lot of magic, they might counter with anti-magic abilities.
