I disagree with you:
it is often found in fantasy novels :
in the "Diamond throne" from Eddings : a whole bunch of people follows a monotheist religion whereas there existe a lot of gods... they just assume the other are either not real gods : ie either their followers are practicing a kind of witchcraft and are subjects of demons or either these churches are purely abusing there followers' confidence.
It is true that they still believe in demons...
(an other similar fact is found in "Heirs of Alexandria" serie from D.Freer, M Zimmer Bradley and E Flint.)
The main church of the monotheist religion do not consider the others gods as true gods but as mere demons, angels... and thus less important than there own god... or invention. Nobody said that religion has to follows some objective reality... only that they believe their's...
another thing : where is there a patch if the mode only gives me white flags, does the patch in FfH2 works for FfH 1 ?
