can you add something like
this Assimilation: With this option selected captured cities retain their original build abilities. So if you capture an Egyptian city you will be able to build War Chariots (Egyptian UU) and Obelisks (Egyptian UB) in it. If you capture a Roman city you can build Praetorians and Forums in that city. Captured cities will not be able to build your real civilization units and buildings, so if you are playing as Babylon and you capture an Egyptian city you won't be able to build Bowmen (Babylonian UU) in it. You can now build diverse empires where samurai are trained in your Japonese holdings while your German territories enjoy the benifits of their Assembly Plants.
