I completely forgot about extra culture from golden ages
I decided which policy path i will take. It gonna be 3 from Piety for +33% culture form cities with at least 1 wonder then finish Freedom. I will complete Piety, go for Liberty then i will finish with either Commerce or Patronnage.
I will build a wonder in each cities as fast as i can from now. I will surely start Oracle into another city than capital, Pisa for another and PT(from a ge) for last one.
And yes Moriarte i'm pretty sure it's better to settle ALL gr. artists excepted for the last 20-30 turns.
