From Adventureland to Abstraction: How Scott Adams' Games Shaped Interactive Storytelling 

Teaching Data Abstraction through text adventures - it didn't take long to get the students hooked A level Computing.

Back in the late 1970s, long before high-definition graphics or sprawling open worlds, a revolution in gaming quietly began with a blinking cursor and a simple prompt:

"You are in a forest. Exits are north, south, and west. What now?"

This was Adventureland (1978), created by Scott Adams—not the Dilbert cartoonist, but a pioneer in early computer gaming. His work helped shape the genre we now call interactive fiction, and beneath the surface of these deceptively simple games lies a powerful lesson in data abstraction.

The Rise of the Text Adventure

Scott Adams' Adventureland was one of the very first text adventure games written for microcomputers. Players navigated through a world described in short text phrases, typing commands like “GET LAMP” or “GO NORTH” to interact with the environment.

These games had to fit into minuscule memory footprints—often less than 16 kilobytes. That constraint forced Adams to structure his games efficiently, paving the way for modular and abstracted programming. It’s this design approach that also laid the foundation for future games like Zork, The Hobbit, and even modern narrative engines like Twine or Ink.

What Is Data Abstraction?

At its core, data abstraction is about simplifying complex systems by separating their function from their implementation. You don’t need to know how something works under the hood—only what it does.

In gaming terms, this means treating a "room," "item," or "command" as a type of object with properties and behaviours. This design philosophy allowed developers to build huge game worlds from reusable building blocks.

How It Worked in Scott Adams’ Games

Let’s look under the hood of one of Adams’ adventures:

• Each location is assigned an ID and has properties like a name, description, and list of exits.

• Objects (like keys, swords, or food) are defined separately, with flags such as "carried," "edible," or "hidden."

• Commands are parsed using simple two-word structures (e.g., VERB + NOUN), reducing linguistic complexity.

All this was stored as data tables rather than hard-coded logic. This separation of game data from game engine allowed Adams to quickly create new adventures by swapping out the scenario files while reusing the same underlying interpreter.

This was data abstraction in action—long before most computer science students were learning about it!

Zork and the Graphical Leap

Meanwhile, at MIT, a team was developing Zork, a much larger and more sophisticated text adventure. They took data abstraction even further by designing a domain-specific language called ZIL (Zork Implementation Language) that compiled into a virtual machine known as the Z-machine.

This allowed Zork and its successors (published by Infocom) to run on a wide variety of platforms. The Z-machine, like Adams’ engine, handled the core logic, while the adventure content existed as abstract data definitions.

Later graphical games like King’s Quest by Sierra would still rely on similar abstraction principles—only now with visual components attached to data objects like rooms, characters, and events.

Lessons for Modern Developers

Whether you’re building a game in Unity, crafting a branching narrative in Twine, or teaching students how to code, the ideas Scott Adams implemented remain relevant:

• Separate logic from content: Keep your game engine and your story data distinct.

• Use objects and states: Rooms, items, characters—they’re all just structured data with properties.

• Build tools around simplicity: Two-word command parsers might be primitive, but they were powerful and intuitive for early players.

Try It Yourself!

Want to explore these ideas further? Here are some suggestions:

• Try recreating a Scott Adams-style adventure using Python dictionaries or JSON files to hold room and object data.

• Build a simple parser that accepts "verb noun" commands.

• Extend your game by adding a graphical interface—but keep the underlying data structure abstract and modular.
