Don Daglow

In 1971, Daglow was studying playwriting at Pomona College in Claremont, California. A computer terminal connected to the Claremont Colleges PDP-10 mainframe computer was set up in his dorm, and he saw this as a new form of writing. Like Kelton Flinn, another prolific game designer of the 1970s, his nine years of computer access as a student, grad student and grad school instructor throughout the 1970s gave him time to build a large body of major titles. Unlike Daglow and Flinn, most college students in the early 1970s lost all access to computers when they graduated, since home computers had not yet been invented.

Some of Daglow's titles were distributed to universities by the DECUS program-sharing organization, earning popularity in the free-play era of 1970s college gaming.

His best known games and experiments of this era include:

Baseball (1971) — A member of Society for American Baseball Research, Daglow created the first interactive computer baseball game, allowing players to manage the game as it unfolded. It appeared ten years after John Burgeson wrote the first baseball simulation game, on an IBM 1620 at an IBM lab in Akron, Ohio. Daglow continued to expand Baseball throughout the 1970s, and ported the game to the Apple II in 1981, adding graphics in 1982. The simulation model in the Apple version in turn was ported to the Intellivision in 1982 as the basis for Intellivision World Series Baseball.

Star Trek (1971) — One of several popular Star Trek computer games widely played in American colleges during this era, along with Mike Mayfield and Bob Leedom's Star Trek. Daglow's game was "the #2 Star Trek at most schools", garnering him fan mail after it was distributed through DECUS. The game printed out dialogue of characters on the Enterprise, describing the events of a battle with an enemy spaceship. The player could enter in choices, such as moving the Enterprise or firing phasers, and the game would advance accordingly until one of the ships surrendered, fled, or was destroyed.

Ecala (1973) — An improved version of the ELIZA computer conversation program. This project paved the way for his later work by suggesting new kinds of game interfaces.

Dungeon (1975) — The first computer role playing game, based on the then-new Dungeons & Dragons gaming system. The game was steadily expanded over the following five years.

Spanish Translator (1977) — As he experimented with parsers he created a context-sensitive Spanish translation program.

Killer Shrews (1978) — A simulation game based on the cult sci-fi film The Killer Shrews. Players do not have many decisions, and it has a goal to escape the island before the depletion of the food that is there.

Educational Dungeon (1979) — An attempt to make rote computer-aided instruction (CAI) programs more interesting by taking Dungeon and making correct answers propel the story.
