Another thing. Does Graveyard really need Masonry as a tech requirement? Graveyard currently requires both Ceremonial Burial and Masonry. At the moment, Masonry is absolutely bloated for content. It has Walls, Quarry, Despotism/Monument to the Dictator, Sphinx, and shares FOUR other Wonders with different techs. I don't think Masonry should really be a requirement here. You can have mound burials without Masonry, so I think it would be more appropriate just to have Graveyard require Ceremonial Burial.
