Roberta Williams
After Twenty-Five Years of Retirement
In 1979, Roberta played the very first text computer game, Colossal Cave Adventure. Her life changed forever. She immediately played every aspect of the game, as game worlds began to grow in her mind. She started working at her kitchen table on a game design, later presenting it to her husband, Ken, and luring him into programming her pet project. Her determination and obsession to achieve all 350 points of Colossal Cave Adventure became the impetus for what would become the entire adventure game genre.
Forty-five years later, after two decades away — cruising the world, writing, retiring — Roberta and Ken came back to finish what that kitchen-table moment started. And now, Colossal Cave 3D is their first new game in twenty-five years. A perfect, balanced circle.
"I wanted to create worlds where players could explore, solve puzzles, and feel like the story was truly their own."— Roberta Williams
