Alright, so today I finally made it far enough into the tech tree to be able to build Stock Exchanges. After I finished the tech, all of my Banking Centers began upgrading... I figured this would be ok. Then I go and find out that Stock Exchanges do less economic upgrade than Banking Centers. Not only that, but I went to start changing all my Stock Exchanges into banks... and found that it no longer lets me build them.
I was at about 350bc a turn, 100% industrial output. Now im down to -60 and only 90% industrial output. Of course, all my factorys were upgrading to Manufactoring centers, but all my economic buildings dropping from 24% to 15% had a part in the drop as well im sure.
So, could someone explain to me the point in upgrading to Stock Exchanges, if they are worse? The influence/morale is ok, but if I wanted those increased I'd build entertainment centers or ebassys. Dosen't it make since that because they arn't just upgrades of each other, but diffrent improvments all togather, that they should both be buildable instead of just the "advanced version"(Stock exchanges)?
