 Christian developers have made various attempts at the genre including "" in which the player attempts to convert as many civilians in an apocalyptic future as possible by raising their spirit level and shielding them from the corrupting influences of rock-and-roll music and general secularism.The game has been criticized by such anti-violent video game personalities as former attorney Jack Thompson for strategy involving the slaying of infidels and non-believers, and for the ability of players engaged in multi-play modes to play as the Antichrist on the side of the Forces of Satan.Secular non-violent video game designers have emerged from the serious games movement and include such anti-violence titles as "PeaceMaker", a game where the player tries to foster peace between Israelis and Palestinians, and "A Force More Powerful", a nonviolence-themed game designed by Steve York, a documentary filmmaker and director of Bringing Down a Dictator, a non violent resistance film featuring Ivan Marovic, a resistance leader against Slobodan Milošević who was instrumental in bringing him down in 2000.
