My issue with Collins’ claim that she had never heard of Battle Royale is simply that it is foolish and irresponsible for her not to have heard of it. Whether your story is fact or fiction, writing a book always requires at least some amount of research. Before The Hunger Games existed, it was basically impossible to do even the laziest Google search on any of the themes present in these two stories without hitting on loads of Battle Royale stuff. She is either lying or willfully ignorant. Moreover, it is utterly impossible for her publisher not to have known about Battle Royale at some point before the publication of the novel and highly unlikely that they would not have brought this to her attention. Also, Battle Royale was/is not actually obscure among people who read…like at all. The only people who find it obscure are very young people or people who don’t read much.
