The daily income provided jumps significantly after level 7, and is rather nice when maxed (12640 coins since update 0.26), but does not improve further over time. The unit bonus when attacking (+50% when maxed) is the same as the Statue (and stacks), so the Cathedral could be considered as being part Statue, and part (24-6=18 squares) income generator. The Cathedral is moderately sized (4×6=24 squares), providing coins and a military unit boost when attacking. The Statue (and Cathedral etc.) do encourage more militaristic play, if you can get them up a few levels. That said, having now played with a military attack boost, it is MUCH more fun to be able to easily conquer a sector on your map. I suspect that the Statue can’t really achieve that real value level, so it’s mostly a decorative / vanity addition to your city, and helpful to those who really enjoy the PvP battles, or want to use those battles to improve their overall game score. That’s about the value of one Late Middle Ages good per day, or about one expansion space every 4 weeks. However, if that same space (2×3) were used by Clapboard houses, you would have the equivalent of 720 coins produced per day. These are at minimum sufficient to pay back the cost of the space and goods required to build it. It is still hard to figure out the real value of the Statue, but at a guess, I’d think it should give a 5% improvement in your weekly medal rewards, and some goods saved. Since some other later GBs give the same benefit, this is very useful for comparison purposes. The Statue is interesting both because it is the smallest GB (2×3, only 6 spaces!), and the only one with only a single benefit. (Reality will be different of course, but it is a useful gauge/estimate). For the purposes of the latter issue, I made a table where I estimated the output value of GBs in the Early, High and Late Middle Ages, with an assumed standard set of houses and supply production buildings. Further complications are that each GB has different combinations of benefits, and some benefits are worth more in different ages (or when boosting better buildings). However, it uses less than half as much space (4×4=16 vs 6×6=36 squares).

The Lighthouse, for example, produces 12% less goods than St Marks. Likewise, the space needed is also a big factor. So is the Deal Castle 267 times better than the Tower? Probably not). Building the Deal Castle though, requires Colonial Age goods that would require 800,000 each in supplies and coins to produce. (A Tower of Babel, for example, costs the equivalent of 3000 coins and 3000 supplies to produce the 150 Bronze Age goods needed. In part, this is because the initial resource costs of GBs go up significantly – by nearly a factor of 3 for each age. It’s difficult to figure out exactly how much though, and whether the difference is fair or not. On reviewing their benefits, it is clear that some ARE better than others. In effect, they are like large Premium buildings (often much better!), which makes sense given that many were at least partially bought with diamonds, and/or require a LOT of investment to complete. Great Buildings are definitely better and more interesting than regular buildings.
