If the purpose of this project is to promote cooperation between alliances, then it isn't a good way to do that. From what I understand it, you have to find nations with a government type and social and economic policies that are most compatible with yours to make the most money using this project. If that's the case, then the most profitable types and policies will be found quickly and become the meta for the rest of the project;s existence, and alliances will mandate certain government types and social/economic policies to be chosen by their members, thereby ensuring the benefits of the projects stays within the alliance.
Considering that there are plenty of projects that either boost a nation's income, this projects seems unnecessary at the moment.
I'm not sure how this adds anything to the game. Is this supposed to be a source of income without adding money to the economy of Orbis?
