It seems that the longer you have had a building (or wonder), the more culture it generates per turn.
How exactly does the culture value (per turn) increase over time for individual buildings? Does it increase the same amount (+x) for each building every y turns? Is it maybe multiplied (*z) every y turns? Is there a cap for this?
