I just bought the game and played a game with some friends yesterday. We were a bit uncertain about the mechanics of some of the wonders though, mainly the wonders that have abilities that happen at start of turn (i.e. The Collossus, Hanging Gardens, Panama Canal, Sidney Opera House).
The Hanging Garders says 'Start of turn: build a figure in the squrare containing the Hanging Gardens for free'. Does this happen every single turn as long as the wonder is active (and you have figures in your stack), or just once (the first turn after you build the wonder)? Same question for all the others. If you have the Opera House, do you advance on the culture track every turn? Do you get one coin every turn when you have the Canal?
We thought this was a bit much, so we treated it as though these wonders had a one time only effect, at the start of the first turn after you build the wonder. Did we interpret this correct?
Thanks in advance if anyone wants to answer.
