All Battlestar Galactica productions share the premise that in a distant part of the universe, a human civilization has extended to a group of planets known as the Twelve Colonies, to which they have migrated from their ancestral homeworld of Kobol. The Twelve Colonies have been engaged in a lengthy war with a cybernetic race known as the Cylons, whose goal is the extermination of the human species. The Cylons offer peace to the humans, which proves to be a ruse. With the aid of a human named Baltar, the Cylons carry out a massive nuclear attack on the Twelve Colonies and on the Colonial Fleet of starships that protect them. These attacks devastate the Colonial Fleet, lay waste to the Colonies, and virtually destroy all but a small remaining population. Scattered survivors flee into outer space aboard a ragtag array of spaceworthy ships. Of the entire Colonial battle fleet, only the Battlestar Galactica, a gigantic battleship and spacecraft carrier, appears to have survived the Cylon attack. Under the leadership of Commander Adama, the Galactica and the pilots of "Viper fighters" lead a fugitive fleet of survivors in search of the fabled thirteenth colony known as Earth.
These Battlestar Galactica softcover novelisations were written by Glen A. Larson with the authors listed below. They were critically disparaged, but proved popular, with the first novel selling over a million copies within its first year. The first ten novels adapt the episode of the same title except as indicated. All novels except Battlestar Galactica 14: Surrender the Galactica! (ACE publishing) were originally published by Berkley, and have been republished, recently, by I Books, which called them Battlestar Galactica Classic to differentiate it from the reimagined series. The episodic novels featured expanded scenes, excerpts from "The Adama Journals", more background on the characters, and the expansion of the ragtag fleet to almost 22,000 ships as opposed to the 220 in the TV series.
In November 2003, shortly before the premiere of the re-imagined TV series, Sierra released a 3D space combat Battlestar Galactica computer game for the original Xbox, PlayStation 2, and PC. The game took place 40 years before the original series and featured an ensign Adama flying a Viper during the Cylon war. The game was developed by Warthog.
In 2018, Ares Games released Battlestar Galactica: Starship Battles, a miniature game by Andrea Angiolino and Andrea Mainini simulating space duels between Vipers and Raiders, with expansions including further models. The game is based on the 2003 re-imagined series, but the license will also allow use of spaceships from the original series, with a game approach similar to Wings of War. 2b1af7f3a8
