How a 1977 wargame became so addictive it caused students to fail their classes
In short: Conceived by Walter Bright, Empire began as a tedious board game before evolving into a digital phenomenon. Its simple, turn-based mechanics for exploring maps and capturing cities proved so compelling that it sparked widespread obsession, eventually influencing legendary titles like Civilization and shaping the landscape of modern strategy gaming.
Walter Bright first conceptualized Empire in 1971, drawing inspiration from board games like Risk and Stratego, as well as war films. He initially found the manual gameplay exhausting, but realized that a computer could manage the complex rules and serve as a challenging opponent. By 1977, he had rewritten the game in FORTRAN for the PDP-10 at Caltech. The game was so engaging that it reportedly led to video game addiction among students, with some failing their classes as a result.
The game's history is defined by its viral spread. After someone illicitly copied the source code from Caltech, it circulated through various networks, eventually reaching Herb Jacobs and Dave Mitton, who ported it to VAX/VMS. This version was distributed by DECUS, bringing the game to a wider audience. Bright later pursued commercial success, licensing the game to Interstel in the 1980s, which led to releases on platforms like the Commodore 64 and Apple II. The game's influence was profound; Sid Meier has explicitly credited Empire as an inspiration for his Civilization series.
Throughout the 1990s and 2000s, the franchise continued to evolve. Empire Deluxe, released in 1993, added advanced units and larger maps, while later iterations by Killer Bee Software brought the title to modern operating systems. Despite its humble origins as a text-based project, Empire was recognized by Computer Gaming World in 1996 as the 8th-best computer game ever released, cementing its legacy as a foundational pillar of the strategy genre.
