Here are the new tier 4 governments: Synthetic Technocracy (Optimization Imperative): 1 Military, 2 Economic, 1 Diplomatic, 5 Wildcard policy slots. +3 Power in all cities, and +30% Production towards all city projects. -10% Tourism. Corporate Libertarianism (Venture Politics): 2 Military, 1 Economic, 1 Diplomatic, 5 Wildcard policy slots. Commercial Hubs and Encampments provide cities with +10% production, bonus to accumulating resources with improvements. -10% Science. Digital Democracy (Distributed Sovereignty): 1 Military, 1 Economic, 2 Diplomatic, 5 Wildcard policy slots. +2 Amenities in all cities, and +2 Culture per specialty district. -3 Combat Strength for all units. To me it seems that they are not worth it especially if you are going for domination victory. Fascism is simply better than any of the new governments if you are going for domination. I also feel like Corporate Libertarianism is clearly weakest tier 4 government and I dont really see it being great for any victory type. We must also remember that some of the best policy cards like New deal or Martial law can only be used in specific tier 4 government. I feel that the devs made them so bad, because they wanted them to be on the same level as tier 3 governments or only little stronger. So you have to actually think if it makes more sense to change your government or stay in the old tier 3 government.
