160 faith to purchase?

[Artifex1]

In some games I see 160 faith to purchase buildings and missionaries..then in others 200 faith.

Both with same empire.

What am I missing? Why is it cheaper in some games?

It varies depending on your game speed and era.

There's a policy within the Piety tree that gives a 20% discount to faith buildings.

 

[TLHeart]

There is also a belief that gives a 20% reduction to the cost of missionaries and prophets

The faith cost of purchases increases per era. Purchasing with faith gets more expensive in the later eras.

Different cities can have different religions with different bonuses.
