Seems you didnt understood me or i didnt been so clear - i've built it many times, but i do not build it... (lately) because i dont see the sense
I play Immortal/Deity games, where you normally do not build castles in every city, except if you go honor, but if you go honor, you normally do not build (many/any) wonders either...(hint: you conquer them)
This wonder comes when happiness is not an issue (except super-wide warmonger games for which it designed) but alas its very situational to build in warmonger game, and its culture bonus laughable given it works at wide base (per city + hammer investment, totally useless for inner rim cities )
Also i do play information era , modern era MPs, where is huble is awesome
Also i play OCC games , in which i can easilly build it but i wont get much of use from it , actually
hubble good for any prolongated game, and huge advantage in late eras
Nauch is just situational wonder, i built when i played Emperor and lower levels,
Normally this wonder have better rivals to build at same era it comes
hope this is clear
I just don't agree. Even with a single city, Neuschwanstein plus a regular Castle would give you 9 Gold, 6 Culture, and 3 Happiness. That's pretty damn good for a single wonder that can be "easily built", as you say, and you're likely to already have the Castle anyway since it's OCC.
Neuschwanstein is also great for a tall, 3-5 city empire. You'd get 21 Gold, 14 Culture, and 7 Happiness from 5 cities with Castles. And don't forget that these are base values, modified by other buildings (e.g. Markets) and policies (e.g. Commerce opener). Even if you don't need the Happiness (and you probably don't since Happiness is too abundant right now), the Gold alone is worth it.
In a wide empire with 10, 15, or even more cities, you might not have a Castle in every city, but you'll probably have one in at least a handful of cities, so you'll still get the bonus that a tall empire gets. As you progress and Castles become increasingly cheaper to build (relatively), there's nothing to stop you from building a few more to increase the bonus from Neuschwanstein. It's the wonder that just keeps on giving! Even puppet empires do well with Neuschwanstein because the AI tends to prioritize Castles for some reason.
On the other hand, Hubble Telescope is useful for one victory condition (Science), and either comes too late to matter or makes such a big difference that it's overpowering. Either way, it's no good. Science victories are already the easiest to get on higher difficulty levels and trivializing them with Hubble isn't all that impressive, to me.
And whether you like it or not, the vast majority of games are probably single player and starting in the Ancient Era. If you want to talk about which wonders are "situational", then you should probably consider typical games instead of your very niche non-Ancient MP games.
I seldom feel any great urgency to build it... Maybe I need to think about it a little more...
