My list of wonders ranked from best to worst:
(I usually play on King or Emperor)
1. Hoover Dam
2. Adam Smith
3. Michaelangelo's Chapel
4. Leo's Workshop
5. Magellan's Exp.
6. Js Bach (lower than Mike's 'cause you have to research a dead-end to get it)
7. Sun Tzu
8. Colossus
9. Pyramids
10. King Richard
11. Great Library (I've been playing the game since the very beginning and have yet to figure out how a free tech can be a bad thing. Unless it's communism, which GL can't give you. It's not like you have to sacrifice your own tech lines for this.)
12. Seti Program (Sure it comes late, but I like getting to Stealth as soon as possible, and even worse, I can't let anyone else get a tech boost.)
13. Women's Suffrage (eliminates the need to ever research Communism)
14. Isaac Newton (beats CO because I'm more likely to grab Theory of Gravity early than Astronomy early.)
15. Darwin's Voyage
16. Oracle (lets me have bigger cities early on, which I like. Sucks when it expires though, unless you get Mike's in time, cause there really is no other remedy.)
17. Copernicus
18. Statue Of Liberty
19. Hanging Gardens (now this is one I think expires too early.)
20. Cure For Cancer (way too expensive when all it gives you is 1 happy person per city when most of your cities are 15+ anyway.
21. Marco Polo (yeah, I know it helps you trade and everything, which is the best way to win the game, but if sit around building caravans and freights all game all the time, it'll bore me.)
22. Litehouse (it's underrated, but ultimately not very useful. I think the effects should have been made permanent.)
23. Great Wall (I build this so unoften that I can't even remember now what makes it expire. At least it comes during a time where it's ok to reject the forced peace offers.)
24. The Apollo (It's nice having the whole map, but every civ gets every benefit this wonder brings. Who cares. Why does every civ have to discover each tech on its own, but whatever it is that The Apollo brings that enables anyone to build a spaceship is shared by whoever builds The Apollo? Makes no sense at all. Make them build their own space program.)
25. Shakespeare (I probably build this about once in every 20 games, and actually utilize it once in every 20 of those games. Does nothing.)
26. Eiffel Tower (I don't want the benefits this brings.)
27. Manhattan (Same here...)
28. United Nations (and same here. I hate this wonder and I avoid building it at all costs. The manual & strategy guide tries to make it look like this does us a favor by giving us a 50% chance of senate interference. But if the civ you're fighting demands your money, and you don't have UN, you don't need to worry about the senate. If I'm in a war, I will not tolerate not getting the last shot, and I just can't stand the feeling whenever the Ai can take one of my size-2 cities, start diplomacy, and be on the wrong side of the coin when the senate raises the white flag behind my back. I like to destroy this wonder so that nobody can hide behind it when I'm attacking them, too. What a pain.)
. Anyhow, lots of other better early wonders to get and Wall is totally worthless in mulitplayer except for the free city walls. Expires too early to be that useful I think.
