One of the players in my campaign, a high level cleric, wants to build a temple. Anyone know of any good sources of info for building a temple, how to figure out how many worshipers it'll have, what kind of revenue, etc? Thanks guys!
Although Defenders of the Faith is old (written during 3.0 days), it does have a section on PCs running temples of their deities. I don't think it gets down to the nitty gritty numerical stuff on worshippers or revenue, but it does give general advice.
