Besides the Stele and the Pyramid (and maybe the Floating Gardens), is there any reason why Burial Tomb shouldn't be considered #4 or #5? The +2 is useful in any scenario (during any era), especially with the clash of ideologies late-game. The no maintenance makes it a viable early-game building--a circus on steroids (or half a luxury). Also, it makes getting the grand temple an easier feat, contributing to offensive and defensive religious pressure earlier. Does anyone actually consider the capturing penalty a serious downside? I usually play a faith/piety game, so a +2 , +3 , and +25% building is hard to turn down, I feel. What does everyone else think?
