Bazaar - 28
Floating Gardens - 26
Hanse- 21
Paper Maker- 24
Pyramid- 38
Stele- 35
Lets see, in a standard 4 city tall strategy, what will these give you by the late game?
Bazaar - +40ish gpt if you can sell everything. If you have DoF it can even be sold in bulk and get you more money earlier.
Floating Gardens - +15% food (quite a bit, not sure about specifics, but a ton.)
Hanse - +40% production (assuming no Petra or Colossus. Again, not familiar enough to know what that raw number is, but it's got to be a ton. Comes at the cost of a bit of gold, although getting patronage and completing trade route quests can lessen that downside.
Pyramid - +8 science, +4 faith, but the benefits are far greater because of the science and faith early snowball effect (better religion without messing up your tech path). You get more turns of civil service and fertilizer than everyone else, the ability to get more wonders because of your tech lead, and your religion (which could theoretically come solely from this and be good) is giving you way more benefits.
Stele - +8 faith, but also puts you 10ish turns ahead in social policy acquisition from the start, and the religious benefits add up to give you awesomeness. Also allows you to get a really strong religion while strengthening instead of weakening the start game, which religion normally does.
Paper Maker - +12 gold per turn.
Sure, the paper maker is good early game, but the effects don't snowball the way these other buildings do. I also don't think the early game benefits are as powerful or can lead to as big of an advantage as the faith gainers can. It's a nice building certainly, but its effects are sort of like the wat's, but a bit better. It's really nice because you want one in every city anyway, but it's not the same game changer that the other buildings are.
