The funny thing is, I rarely build forbidden City, and over half of the time I can't get great Pyramid because it is too early so in recent games I just skip it unless I play China. These "general" wonders are good to have, but are not as game changing when compared with those "specialized" wonders like big Ben (money to essentially buy a science victory), Venetian arsenal (quarantee a domination in water-bath maps), Petra (with over 5 desert hills, resources and Oasis, one Petra city can easily produce more than 2 cities combined), Eiffel (if going for the seaside resort rush), great Zimbabwe (especially if you also control Carthage).... This kind of elimination is inherently for the safe choices
