I've not yet altered the Civics tree, except for moving the buildings and units to the tech tree. Altering the civics tree is the next job . This is an early version of a mod that will run and run, and become more detailed as versions go by. Once we can add 2D art, then you'll see some big changes.
Incidentally, the plan for the Civics tree is that it will be government policy + new types of government + diplomatic abilities like open borders - but no buildings/units/wonders, they'll be focussed within the tech tree.
