the titles already summarizes the issue. the reason is
a) historically cathedrals were build on the foundations of older churches.
b) the cities building list gets a bit cleaner.
what i would do is just add all temples attribute to the cathedrals so there won't be much of a game change. (building prerequisite of cathedrals will be downed to one temple - since it replaces another one, so there won't be any change with that prerequisite either).
only thing i intend to change is the incense happiness bonus. it can grow too big with too many cathedrals (up to +9
) so i'd switch that to a static gold gain.
additionally some religious specific wonders could replace cathedrals. in this case they'd also inherit their attributes from the cathedrals they replace plus the statistics they had prior to that. so no game relevant change done except some list shortening.
