I'm assuming I'm not the first to think of this, so what are the arguments for and against having alignments as civics?
The way I imagine it, leaders would start with their default alignments, but players could change at will. Good would be available with Way of the Wise, Evil with Wicked. There would be alignment requirements on certain civics, as well as religions. This would keep the mechanic of religions changing your alignment. A player could switch to neutral anytime they want for the diplomatic bonuses, but not have certain units, civics, etc available to them. Anyway, if a player values diplomacy that much, then they should be neutral.
As far as I know, religions are the only way to change your alignments short of XML. I think alignment civics could add more role-playability and not detract from flavor.
