Stupas: Its time to do something about this building. Its garbage. Pagodas: So in general I find when your going pagadas on Standard its reasonable to get 3 religions. 4 is a real corner case in my experience. So pagodas gives +3 food, prod, science, culture, faith, -1 boredom, but none of the religious boosters that the other buildings get. I don't know, they are decent yields but I think the synagogue and mosque are way better than this, and pagodas tend to attract more religious division than the building stamps out.
