Guide:Great Buildings Analysis

This is a comparison of every Great Building of the game with their equivalent. This article is based on my own opinion, but all idea will be clearly explained with math and so. I took the liberty to create a page, because this comparison will be very long. All data belongs to the wikia and thus can be false, i haven't verified any values.
This page is ongoing. All result will be added gradualy as I get the data and process it.

First, I will say some things that could surprise some people, so I will explain everything before starting the comparison :

• Happiness is useless as long as you have a Lighthouse (or Royal Albert Hall), a Saint-Mark Cathedral and reached a certain Age (math below). To make your population happy (for a quest for example), all you need is the Enthusiasm Boost in the Tavern (costs 3500 Tavern silver).
• ... (in progress)

Now, I will enter in the main subject. It will be separated in two parts : one with the base Buildings data and one with the Great Buildings data.

Great Buildings :

Observatory

Usefulness : Very high
Very useful at the beginning due to it's small footprint, to unlock levels in Guild Expedition. Any level higher than level 4-5 would be useless if the guild doesn't participate in Guild Wars.

Temple of Relics

Usefulness : Very high
This Great Building is probably the best of all, because of all the rare objects / buildings, that you can get with it. On the top of them, we can find :

• Culture Farm (for more details, see my comment on it's page)
• Renovation Kit
• Youth Fountain

Tower of Babel

Usefulness : Very low
This building is good, but it could make you poor or unhappy very quickly and looses almost all interest in modern Ages.

Statue of Zeus

Usefulness : Very High (fighter only)
Having the smallest footprint among all Great Building, this building is a must-have, due to the rarity of the attack bonus.
