At the 2011 Auckland Writers and Readers Festival, former Batgirl writer Dylan Horrocks said that the writers were told by editorial that the War Games crossover would “involve some kind of Gang War in Gotham” and involve Stephanie Brown's death. Due to the disagreeable nature of deliberatly planning drawn out torture scenes and high school massacres, both Horrocks and Nightwing writer Devin Grayson opposed the storyline during planning, to the extent that Horrocks deliberately kept the scripts of Batgirl out of several key events in the story.
