i always turn off religious victory because its more of a nuisance than anything. i like the idea of an increase in production speed based upon how much you have contributed to the AC. i think that any ritual that would give you a hell victory should be in stages. thats because i dont think your fellow followers of the AV would be happy that you are gaining more favor. I dont see other civs with AV as being a "friend" relationship but more as "i wont kill you until last" kind of thing. that way if it was done in stages, it would give them time try to kill whoever was getting close.
