@Thunderbrd I did not want a 1:1 ratio of science to gold. Mainly because many buildings improve over time. Thus the -gold can be sometimes worse or better than the science. Likewise many buildings have other factors not related to science. And like I said this is also applied to other types of buildings. School of Scribes is in the case where its more expensive to get science at the rate of gold. Note this is independent of the slider and many other factors. Its a positive if you have maxed your slider and cannot produce any more science. And yes commerce would be bad since it involves science and gold. And in your last paragraph that is right on. To benefit from the science buildings you need to have a balance budget. These are the types of dynamics in the Sim City games (specifically 4) where if you did not have a balanced budget then you could not pay for your schools and thus education would drop. If you balanced your income than schools could work right and your EQ would rise. While we don't have exactly, that its close enough. This is one of the factors I loved in Sim City since it mirrors some real world dynamics. Such as government getting into debt and cannot pay for the nice things they built in more profitable times. In short you have to be smart in how and what you build in your cities. There is a time and place for most every building, the trick is to build them at those times. For instance if you build only -gold buildings you are going to go bankrupt. But if you never build any then you are going to suffer from crime, disease, fire and other factors like low science and health.
