They should come out with games for all religions. I can just imagine it now.
Atheist Killers - Kill all the religious people and stop the spreading of pointless dogma.
Pagan survival - Fight off the crazy Christians that are trying to burn anyone that wont convert.
Scientology and celebrities - it is your job as a celebrity to begin converting other celebs to Scientology and try to convert the world by telling them it's cool.
Islam hunters - Command your army to commit suicide and kill non believers in the name of Allah.
