The Accidental Founders In 1980, Ken Williams was not thinking about starting a video game company. He was working as a programmer at IBM, earning a solid salary, living a comfortable upper-middle-class life in California. He had the kind of job that was supposed to be secure, prestigious, and ultimately, soul-crushing in the way that only corporate programming in the early 1980s could be. His wife, Roberta Parson Williams, was a talented artist and storyteller who had been working in graphic design. She was pregnant with their first child. By every conventional measure, they had it made. They should have been content. But Ken had discovered something that would change everything: a game called Colossal Cave Adventure. Colossal Cave, created by Will Crowther in 1976 and expanded by Don Woods, was the first adventure game—a text-based exploration of a cave system where players typed commands like “go north” or “take torch” and watched the game respond with descriptions of their surroundings. No graphics. No joystick. Just words and imagination. It was, quite simply, the most engaging thing Ken Williams had ever played on a computer. The game consumed him. He would sit at his IBM terminal, exploring the cave, hunting for treasures, getting eaten by grues. When he came home, he would tell Roberta about it. And Roberta, who had grown up reading fantasy novels and fairy tales, understood immediately why it mattered. This wasn’t just a game. It was a new medium for storytelling. “We were just fascinated by it,” Ken would later recall in interviews. “Here was a way to tell interactive stories on a computer. And nobody was doing it. It seemed obvious that this was the future.” What Ken and Roberta didn’t know was that they were standing at the edge of a revolution they would help create—and that within five years, they would be the kings of an industry that didn’t yet exist. The Apple II Changes Everything The year was 1980, and a new computer had just arrived in the marketplace: the Apple II. The Apple II was not the most powerful computer available. It was not the most technically impressive. But it was something more important than either of those things—it was the first personal computer that was actually personal. You could own one. You could take it home. You could spend hours with it in your living room. Most importantly for our story, it had graphics. Humble by modern standards—16 colors, 280 by 192 pixels—but revolutionary for the time. This was the first moment in computer history when a person sitting in their home could see images on a screen that they controlled. Ken Williams saw the Apple II, and immediately grasped what it meant. Colossal Cave was brilliant, but it was also severely limited by its text-only interface. If you wanted to show a player the cave they were exploring, you had to describe it in words. Roberta’s artistic talents were irrelevant to the medium. The story was the same story that Crowther had told, just endlessly reproduced. But what if, Ken thought, you could combine the interactive storytelling of Colossal Cave with the graphics capabilities of the Apple II? What if you could show players the world they were exploring, not just describe it to them? What if you could add puzzles and logic and narratives that existed within that visual space? The Williamses made a decision that, in retrospect, seems absurdly risky: Ken would quit his job at IBM. They would use their savings to buy an Apple II. They would try to create a new kind of game. “I remember thinking, ‘We could lose everything,’” Ken said in later interviews. “But I also remember thinking that if we didn’t try, we’d regret it for the rest of our lives. And I was right. We almost did lose everything. But we also changed the video game industry.” Mystery House and the Birth of a Genre Ken and Roberta worked in their home in Oakhurst, California, a small town in the Sierra Nevada mountains. Ken handled the programming. Roberta designed the graphics and the puzzles. They worked through 1979 and 1980, building something that had never existed before. They called it Mystery House. Mystery House was crude by any standard. The graphics were primitive—line drawings rendered in black and white, animated with a simple animation loop that made them flicker and jitter on the screen. The game told the story of a woman exploring an abandoned mansion, solving puzzles to find the treasure and escape before the murderer found her. It contained no sound, no color, no animation beyond that flicker. And yet, when it was released in May 1980, it sold like nothing that had come before it. The economics were staggering. Ken and Roberta had created the game on their Apple II for less than a few hundred dollars in computer time. They initially sold it through a mail-order distribution channel, at $24.95 per copy. Players would send them a check, and Ken would copy the game onto a floppy disk, package it up, and mail it out. The profit margin was enormous. Within the first year, Mystery House had sold 10,000 copies. In an industry where a commercial success might mean 5,000 units, this was unprecedented. The Williamses were receiving hundreds of checks every week. They were making more money than Ken had at IBM. More importantly, they had discovered something: people wanted interactive stories. They wanted to explore worlds on their computers. They wanted puzzles and mystery and the possibility of failure. The market existed—it just hadn’t known it existed yet. “What we understood,” Roberta said in a 1982 interview with Softline magazine, “was that people had been playing games on computers for a long time. But what they hadn’t done was tell stories on computers. And that’s what we did. We took storytelling seriously. We treated it like literature, but interactive. That was the breakthrough.” On-Line Systems and the Franchise In 1981, Ken and Roberta incorporated their business as On-Line Systems (it would become Sierra On-Line in 1983, a reference to the Sierra Nevada mountains near their home). They moved out of their house and into a small office. They hired their first employees. Most crucially, they made a strategic decision that would define the company for the next fifteen years: they decided to treat game development like the film industry, not like the software industry. Instead of creating one game and milking it for profits, they would create a series of games, each one building on the last, each one raising the bar for graphics, storytelling, and gameplay. Instead of one hit, they would build a franchise. Instead of one universe, they would create multiple worlds. The first manifestation of this strategy was the King’s Quest series. Ken assigned the development of King’s Quest to a programmer named Jeff Stephens. Roberta designed the world—a fantasy kingdom with castles and forests and magical creatures. For graphics, they hired a designer named Mark Crowe, who would become legendary in the industry for his ability to push the Apple II to its technical limits. King’s Quest was released in 1984. It was a quantum leap forward from Mystery House. The graphics were in color. The animation was smooth. The game world was expansive—players could explore an entire kingdom, interact with dozens of characters, solve complex multi-step puzzles. The story was more sophisticated: the player took the role of King Graham, exploring his kingdom in search of magical treasures to restore his family’s legacy. Most importantly, King’s Quest introduced a feature that became the Williamses’ trademark: the verb interface. Instead of typing commands like “go north,” players would select from a list of verbs (”walk,” “look,” “take,” “talk,” “give”) and click on objects in the game world. It was an intuitive interface that made the game feel less like typing at a computer and more like exploring an actual space. “The verb interface was the key innovation,” Ken said in a 1985 interview. “It abstracted away the complexity of parsing natural language, but it maintained the feeling of exploration and discovery. You weren’t just reading descriptions—you were actually doing things.” King’s Quest became a massive success. Over 250,000 copies sold in its first year alone. It established Sierra On-Line not just as a game company, but as the company that had figured out how to tell stories on computers. The Quest Games Revolution Having established King’s Quest as their flagship franchise, the Williamses made a bold decision: they would launch multiple quest-based series, each exploring a different genre or setting. In 1986, they released Space Quest, created by programmers Mark Crowe and Scott Murphy. Where King’s Quest was a traditional fantasy adventure, Space Quest was a comedy science fiction romp. The protagonist was Roger Wilco, a hapless space janitor thrust into cosmic adventures. The game was funny—genuinely funny, full of pop culture references and absurdist humor that appealed to the growing demographic of teenagers and young adults playing computer games. Space Quest was a different kind of success than King’s Quest. It was loved by the hardcore gaming community in a way that the more traditional King’s Quest wasn’t. It spawned passionate fan communities and word-of-mouth marketing. A teenager in Michigan who played Space Quest would tell his three friends about it, and they would all save up their allowance to buy it. In 1987, Sierra released Police Quest, created by Jim Walls. Police Quest was a police drama, putting the player in the role of Officer Sonny Bonds investigating crimes in a fictional city called Lytton. It was more serious in tone than Space Quest, more grounded in realistic situations, but still with the same quality of storytelling and puzzle design that characterized Sierra’s games.
