the game already has a political element to it already. for doing some missions you gain political favor points that can be spent on special structures like the soldier outpost etc. a new tier of tech is really not needed. just ask dan to add a few more of these structures to the mission trees. that is the most simplistic way to get what you want.

When it comes to Political Favors, you are just helping the politicians. I am trying to introduce a way for a player to become more like those politicians. If not, at least there can be some way to slightly increase the chance of gaining Political Favors from missions (only slightly).
