I noticed two errors about this wonder:
1.) When finishing Big Ben, you get a popup screen. There is no message about the -25% purchase cost
2.) The effect of this wonder should be, to reduce the purchase cost by 25%, right? Like instead of 500g it costs 375g (without any other effects). It did not do that and I think I know what happens: The purchase cost is given in percent of production cost. So if something costs 300% original, it costs now 275%.
This is a very important wonder if you want to go for mass gold with villages, then purchase items.
