I had this idea years ago when trying to write a civilization type game: Colleges with focuses.
A city can build a college, but it needs to have one focus, such as economics, military, science, or a number of other topic. The college will provide a nominal amount of points for all focuses, but will provide the most towards its chosen focus.
Later, a college can be upgraded to a University, which will provide for up to three focuses.
There can also be a wonder, such as Oxford University, that provides equal points for all focuses.
