No, Christians did not make this game. If anyone of you know about the Anime called, "Neo Genesis Evangelion" you would recall that much of it is a reference to Christianity. There are angels sent to destroy earth. There is a cross whenever the angels set off an explosion. There are references to Adam and Eve. However, the morality and actions of the "heroes" in no way portray Christ. Simply because something has a reference to Christianity does not mean it was created by Christians. in fact, the only reason there is any reference to Christianity in Evangelion is because the author/director didn't think anyone in Japan would get the references.
