Downvote goes to the
Bolshoi Theatre. I think the Bolshoi Theatre has the following problems: it offers only a trivial amount of Great Person Points for how late in the game it comes, and probably won't even earn you a full Great Person of either type; it has stupidly small number of Great Work slots; and most importantly, the main bonus of two free Civics does not work. Anyone playing the game to a reasonably high-level will be bee-lining the key Civics they want, and, notably, leaving a few 'dead-end' Civics from early on unresearched. Why? Because later on you can switch to them and research them in a single turn to give you really quick policy flexibility. If you build the Bolshoi Theatre, either you a) take the risk that these 'switcher' Civics will be researched, in which case you've just wasted the free Civic on something you could do in a turn and lost all Policy flexibility, or b) you waste a few turns clearing these 'switcher' Civics meaning you now have no Policy flexibility later on. That's a bigger penalty than it looks. In addition, the Bolshoi Theatre also just requires you going over to the wrong side of the Civics tree - frankly, you want to rush Mass Media and that requires you to have been focusing on the top half of the Civics tree, not the bottom half. As such, the Bolshoi Theatre can actually delay you by pushing you to the wrong side.
The reason I've left off the Bolshoi Theatre until now is because for reasons I can't quite work out, I just
never see the AI build this. It's almost unheard of. I usually end building this thing eventually because it just gets left for basically forever and I just like the cool points. But "I build it because it's there" isn't really a strong sentiment in favour.
Upvote goes to the
Statue of Liberty. It's 20% of a Diplomatic Victory. Yes, Diplomatic Victory is meme win condition that isn't fun in the slightest. Neverthelss, it is an extremely viable way to win and the Statue of Liberty gives you a big leg-up on it.
As an aside: I don't think things like the Statue of Liberty, the Cristo Redentor, and the Eiffel Tower should be being down-voted just yet. Yes, they only contribute to one win condition... but they all contribute a
lot to that win condition. To respond to
@Archon_Wing, Ski Resorts absolutely do not replace Seaside Resorts in the slightest - well-placed Seaside Resorts get you waaay more Tourism than Ski Resorts can, they get you ever important Gold for just rushing Builders to spam Forests for more Appeal Tourism or to rapidly build Faith infrastructure from nowhere to help with Rock Bands and the like. The Cristo Redentor then makes them even better on top of that. In addition, if you were attempting a Reliquaries Culture win (the fastest and arguably most powerful sort, albeit under specific conditions) and for whatever reason couldn't quite drag it over the finish line, the Cristo Redentor helps you transition to a later sort.
Only contributing to one Victory Condition is
fine. Nobody pursues every Victory Condition right up until the final turn. At some point, you have to commit to a Victory Condition, because it's the best one available to you or because others are no longer viable (and if not and you feel you can win in loads of different ways, you're ready to graduate to a higher difficulty level!). Generally speaking I have picked what sort of Victory Condition I want to pursue quite firmly by T30 at the absolute latest. Sometimes game events force me into a pivot unexpectedly - e.g. a runaway Kongo on the other side of the map when I wanted to do a Culture Victory. Nevertheless, even forced pivots have basically run out by T100.
The fact that e.g. Petra can play a role in any Victory Condition doesn't make it better than the Statue of Liberty. Why? Because when I use the Statue of Liberty, or the Eiffel Tower, they give a lot of buck for bang, they're a big part of that strategy. Petra... is nice and fun? It gives you a little nudge for anything, but I'd never describe it as an intrinsic or critical part of anything. If I miss it, it's a matter of mild peturbation at worst. If I was going for a National Parks driven Cultural Victory and I miss the Eiffel Tower, that's a much bigger problem.
My view is that the real line-up to go next is the following: Petra, St. Basil's Cathedral, Bolshoi Theatre, and the Apadana, for a number of reasons. None of these are powerful Wonders for any Victory Condition, they're just a fun leg-up if you can catch them. Petra... makes one desert city roughly as good as an ordinary city in terms of terrain yields. This is neat if you're cramped early on, but later on even if you settle to desert you can use one ITR to get basically any City up to the point it can run at least 3 Districts very quickly, and the yields from terrain are not really that important (as is the case for late-game cities). Exactly the same issue for St. Basil's Cathedral, albeit to my mind it is better than Petra because of the role it can have in supporting specifically Cultural Victories under the right conditions. I've outlined the problems with the Bolshoi Theatre above. The Apadana is a little different from the othes because it is actually quite good if you can get it, but it commits you to a very particular strategy to get the most out of it that isn't very flexible, and of course it's extremely difficult to get on higher difficulties and often I feel it is too risky to waste Production on.
, a nice bonus but not overpowering and the AI loves to build it.
