On the subject of Infrastructure, I've been thinking we should do some tests. I'd like to see if we can use a secondary to start projects we want, but have policies finish them very quickly.
So, let's say we want a Governor's Palace in Valleyguard for some reason. We vote for [][Sec] Governor's Palace - Valleyguard, giving us 3 progress at a cost of 3 econ and wealth. If all goes as planned, our policies take it to 8/9, and our FC policy take it to 9/9.
I like Infrastructure passives, but I am thinking we should be willing to pay a bit to direct them better. I'd personally really like to see what special abilities are hidden behind tier 2 versions (and someday tier 3), and this could potentially speed that up.
