Functional is sexy, that's why-- I think part of it for me is... while I have set myself up as a god for the main churchy religion (well, I DID create their world), I'm not interested in the metaphysical aspects (heaven, hell, angels) but the social aspects (churches, faith, interfaith conversations and conversions, cults). Live Sims are more interesting than dead ones, and if I ever need to see what the dead ones are up to, I'll build a special-effects neighborhood. I think we're stuck with the nun, but with any luck she'll be easy enough to default-replace. I have no real idea what she DOES, apart from handle lot zoning.
