A= Game changing wonder.
B= Solid wonders to have in a game
C= Borderline, Niche
D= Poor value
F= Useless or even detrimental.
Great Bath Decent, but impossible to build. Guess for capture like most early wonders. D
Hanging Gardens Not much use, also very hard to build. F
Oracle Good for dedicated GP strategies, but requires you to have some decent space to expand or else you'll be boxed in or just flat out killed. You also need to set this up by building districts quickly or having faith generation. B
Pyramids A fabolous wonder that scales as the game goes along since builders increase in cost the more you build. A
Stonehenge No F
Temple of Artemis Another strong wonder, but it requires you to build it fast at a massive opportunity cost. B
Terracotta Army Can be strong for niche military strategies, problem is building it in time. C
Apadana Good for certain cultural strategies or Sweden but also goes insanely fast and requires more investment for envoys. C (A as China)
Great Lighthouse Faster ships is not game changing D
Great Library It's somewhat interesting, as it keeps giving you boosts throughout the game. Also good for cultural victories B
Colossus-- 1 trade route isn't bad, but a bit w/e. If your empire is a bit small (playing on an island map, it looks better) C
Mahabodhi Temple-- Great for Diplomatic Victories, kinda meh for everything else. B
Macchu Pichu Great Wonder, but I can never build it. N/A
Mausoleum at Halicarnassus Massive value for your great Engineers, plus science and culture are the best yields to get at this point. A
Petra Situational, but makes use out of otherwise useless land. B
Jebel Barkal Can be useful if you lack iron. Faith is okay, but not really that groundbreaking. C
Colosseum-- Largest boost to an entire empire early game. A
Angkor Wat-- For an entire wonder? I think they must have overvalued housing. F
Alhambra Extra Military Slot isn't really necessary by this time, but it has its uses. Probably the weakest of the extra policy wonders. But it is an extra policy. C
University of Sankore Science is good, but you really have to work on the placement for this. B
Hagia Sophia-- Best wonder for a Religious Victory B
Chichen Itza-- Situational like Petra, but the AI has a weird obsession with it so I hate it. C
Kotoku-in-- Warrior Monks for an entire wonder? Extra faith is sorta meh but it could work with Reliquiaries. D
Kilwa Kisiwani-- Potential 15% global boost to multiple yields. This can be the strongest wonder in the entire game under some conditions and at the very least 3 envoys is good. A
Meenakshi Temple Gurus? I've never built one nor this wonder. F
Huey Teocalli Super niche, but notice it affects all lake tiles in your empire. C
Mont St. Michel Home to the cheesiest strategy in the game. A
Great Zimbabwe Solid Gold booster, requires a good setup though. B
St. Basil's Cathedral-- Snow Petra B
Casa de Contratación Great wonder for expansive empires B* (A as Phoenicia)
Taj Mahal Oh look, everyone gets to be Georgia. F
Potala Palace Diplomatic cards start to really pick up mid-game, and this wonder is perfect for it. B
Forbidden City An extra wildcard slot is one of the finest gifts around. A
Venetian Arsenal Strong for naval games, but the thing here is that ancient era ships are so cheap to make and upgrade since ship production cards are +100% production anyways. But I don't want to argue this too heavily. B
Oxford University-- 2 free techs, and the only thing in this game that can do it. Extra science is neat too. A
Bolshoi Theatre Also good for barreling down the last civics you need. B
Hermitage Basically an overpriced art museum that doesn't even theme if not Swedish. I don't even bother with this wonder most of the time in culture victories unless I have nothing better to do, much less outside. D (C as Russia)
Panama Canal-- I feel like this is more of a vanity wonder except in some naval games but it does have its place if you're going to place a strategical city-- may as well go all the way. C
Big Ben-- $$$$$$ and the card. Honestly, I value this over Forbidden City. A
Országház-- Cool favor generator, but I feel that's not the most important thing at this point. C
Statue of Liberty-- Has no use outside of Diplo victories, unless you capture it. C
Ruhr Valley-- Good production boost for your future spaceport city. B
Effel Tower-- Cornerstone of some cultural victories. B (A as Australia and Canada)
Golden Gate Bridge- Another strong addition to cultural victories, but a lot more specific. Best with the above. B
Broadway Decent culture boost and inspiration, but hardly vital. C
Cristo Redento Another component to late culture victories, but significantly more optional than Effel Tower ever since mountain resorts became a thing. C
Estádio do Maracanã Solves all amenity problems, and is usually worth pursuing if the game is going thanks to GS"s longer tech/civic trees. A
Amundsen-Scott Research Station Global boost to production and science. A bit hard to build, but at this point in the game, it's probably not too hard to grab some random pole spot with some deer and go for it. A
Sydney Opera House Music is the worst kind of Great Work and this wonder is expensive. Just build some broadcast centers if you want to hold some that badly. F
