Ender's Game and Hailsham's Game

Great undertakings to the humankind always take the sacrifices of millions. History repeats itself in the real world and in science fiction books.

The Ender's Game is a science fiction book set in an unspecified future where the people have discovered an alien race called "buggers", and the protagonist Andrew "Ender" Wiggin, who has shown exceptional promise is sent to the battle school in space for training at a very young age. Showing leadership skills and incredible tactical abilities, he becomes the captain of the team and eventually leads Earth to destroy the buggers. 

Ender's Game (Movie)

Never Let Me Go and Ender's Game has some incredibly similar qualities. 

1. They are both at a special training school for the benefits of humankind. 

Students at Hailsham receives a unique education from the outside world where they are taught to be creative, protective of their health, disciplined, and about subjects such as sex, donations, and etc. All these special topics and school values are tightly connected to the school's sole purpose – to prepare them for donating their organs. While donating their healthy organs to normal people who are not clones, they contribute their value of preserving other humans' lives to the society and humankind as a whole. 

In Ender's Game, many people who show incredible intelligence and leadership is found by the International Fleet (I.F.) and sent to the battle school located in the orbit of the Earth. They receive physical and mental training every day, as well as tactical classes and virtual battles with the buggers. The ultimate purpose of this school is to destroy the buggers eventually so that Earth will rest assured that they are not the ones destroyed. 

2. The students are both deceived by the administrators.

Both the students at Hailsham or at the battle school in Ender's Game are deceived or kept away from certain information at some point of the story. At Hailsham, the students never learn about certain facts about their origins, fates, or the story behind the school, neither do they know the purpose of Gallery and the aversion of the faculty. The students at the Ender's Game have a rough knowledge of everything. However, as Ender and his team become almost undefeated in their virtual battles with the buggers, they are deceived to believe that their real battle with the buggers is a final virtual battle, meaning that they always think that it's only a fake battle until they actually destroy all the buggers. 

3. There are sacrifices and students are the victims of this undertaking. 

Obviously in Never Let Me Go, the donors, of which the majority is students at Hailsham, are the people that sacrificed their lives for the great cause of donating their healthy organs. In the Ender's Game, thousands of Earth people die in the real battle with buggers who are in a spaceship that Ender sacrificed in order to ultimately destroy the buggers, which is suggested by the book that if Ender knew that it's a real battle, he would have never sacrificed the spaceship of people. Besides the people on the spaceship, the students at the battle school are also the victims of the undertaking. Not only being deceived to kill thousands of Earth people against their will, the students are also criticized centuries after the battle when Earth discovered that buggers were not hostile to Earth at all – they were criticized as inhumane people who destroyed a friendly race with no mercy.
