In 1991, Card made several minor changes to reflect the political climates of the time, including the decline of the Soviet Union. In the afterword of Ender in Exile, Card stated that many of the details in chapter 15 of Ender's Game were modified for use in the subsequent novels and short stories. In order to more closely match the other material, Card has rewritten chapter 15, and plans to offer a revised edition of the book.
