Archaeological Museum (11) 14-3 In Vanilla, this was THE cultural building but it really hasn't kept up with the power creep and Archelogists are really expensive. Still useful, but only in cultural victories and maybe 1 for the boost to Combustion.

You don't build it you buy it, exchanging gold for production and G/E points
You can buy most of the buildings on the list except the government ones, so that's not really an argument for or against. Though I would say it's worse. If you make it with production, at least you have the excuse of saying you have nothing better to build, but instead you're spending gold on this than on the other buildings.
Also buying it for GE points makes no sense whatsoever. The first few GEs cost 2000-3000 gold. A workshop costs 780 gold and only gives you 1 point. Why would you pay 1/3 of the cost of a GE upfront to get it in 120 turns and it's not even guaranteed because it's just 1 ge point. And if you buy more, you might as well just buy the engineer itself.
Even later in the game, GEs don't cost that much; maybe 10k gold but cost 600 GPP.
Workshops simply cost too much gold/production/w.e per Great person point compared to other similar buildings. It's almost 2.5x as expensive as a library, so basically you are only getting 40% of the value for that.
Basically, I find it easier to get GEs with faith or gold than building the actual zones.
People knock the armory over the fact that you might only build a couple of encampments, and that's true... but I'd say the exact same thing about IZs. I might build 2 of these all game, and even then not until much later.
The humorous part is the Armory provides the same yield and does much more.
Also Encampments are also good for Science Victories even if you never declare war because of the Integrated Space Cell, and also the fact that you need a massive stock of Aluminum to run Lagrange. Honestly, I consider Encampments only a bit less important than IZs, and you can get power with hydroelectric dams, solar farms, and also an entire government devoted to it too.
Of course, if you can build multiple nice IZs, it's always wanted but the gulf isn't that big IMO. If you can get 30-40 production from an IZ (not too hard if a factory hits 5-6 cities, it is worth the while)
Anyhow, I suppose dead horse until we talk about factories next time.
