Yeah policy costs late game are ridiculous. combine that with no free Sydney policy and the need to get free religion earlier, for finisher, and kiss culture wins goodbye. Still in my last game I had almost 4 trees filled at finish in non culture game so its still fine. Honor finisher gives the combat strength of the destroyed unit in gold. It does have an issue with the gold not displaying on the map after you finish a unit off though. Songhai with completed Honor can now get an insane amount of gold in war with the new improved carpet of doom.
