I think religion is so bland in Civ 6, it might as well not be there. You either go for a religious victory or ignore it, as so many of the choices affect nothing but faith generation/apostles/missionaries. Even the housing and amenity boosts are basically useless, because constructing a district is not worth it just to get 2 housing and 1 amenity (and that's the best case scenario). Even diplomatically, Civ 6 religion has little impact, except with 3 specific civs. Even then, they can be soothed through other means.This contrasts really poorly with Civ 5, where religion was a significant influence on gameplay whichever direction you went.
