I had proposed that for these civilizations to be proficient in the ‘endgame’ or treaty, the full potential of the square should be achieved with fewer workers.
Before the Aztec priests cost population, and now everyone has priests or healers that cost no population, so the amount needed to reach the potential of the square was reduced to 15 workers.
As an aid for the treaty is very good, the problem is that the square always seemed more boring than the bonfire. Change the square for temples or some kind of administrative building and I’ll be happy.
