Before GaK, it seemed like if you had already built a monument in any of your first 4 cities, it wasted the Legalism buff, which is a free culture building in your first 4 cities (logically it should have given you a temple, but it did not). Well, I built a monument in my capital before taking legalism, and it just gave me a free Amphitheater. My other cities still got monuments, but my capital got its free culture building after all. Just thought you all should know. Sorry if it's been brought up, I saw nothing, and the searches all took me to the vanilla Civ V forums.
