Please, post an example of "later" era that has only ONE expansion in tech tree.You can check how much expansions you can get from tech tree in each era. In modern ones there is only ONE expansion in the tech tree and every new building in the tech tree is bigger and bigger. Diamond expansions and victory expansions are more and more expensive. At the moment I have to pay 400 K medals for victory expansion and 800 diamonds for diamond expansion.
