While Chair acknowledges that there were some cool concepts in mind for how to adapt the science-fiction novel, the studio’s purchase by Gears of War developers Epic — who have a drive to create original IP — put an end to their efforts at making a game based on somebody else’s property.
No great loss for people who had never heard of Ender’s Game, then, and for fans of the book — like fans of anything being adapted into something else, were wary — its probably for the best.
