Later, by elaborating on characters and plotlines depicted in the novel, Card wrote additional books in the Ender's Game series. The novel was published on January 15, 1985. The book originated as a short story of the same name, published in the August 1977 issue of Analog Science Fiction and Fact. The children learn military strategy and leadership by playing increasingly difficult war games, including some in zero gravity, where Ender's tactical genius is revealed. In preparation for an anticipated third invasion, Earth's international military force recruits young children, including the novel's protagonist, Andrew "Ender" Wiggin, to be trained as elite officers. Set at an unspecified date in Earth's future, the novel presents an imperiled humankind after two conflicts with an insectoid alien species they dub "the buggers".

is short for Starways Congress.Ender's Game is a 1985 military science fiction novel by American author Orson Scott Card. Ender arrives on Lusitania in 3150 AX, which launches the events of the second novel in the Ender Saga, Speaker for the Dead. This lines up with the start of the Lionsgate timeline, but the story is much longer in the books than in the movie. The First Formic War starts in 87 BX, which is 2115 AD. Instead of using the Gregorian calendar, the years on the franchise's Wiki database have the suffixes "BX" and "AX," which are shortened versions of "Before Xenocide" and "After Xenocide." The story of Ender's Game takes place between 87 BX and 315o AX in the books. However, the timeline for the books appears to use a completely different system. The timeline for the movie stretches back to before Ender's birth, with the first Formic alien invasion happening between 21. Before the movie adaptation of Ender's Game was released, Lionsgate published a timeline of events in the movie universe, stating that Ender goes to Battle School in 2195 and is promoted to lead Dragon Army in 2198, with the climax of the movie happening in 2201. While the story takes place in the future, the movie and the books follow different timelines.
