Martinus
Emperor
The title is pretty much self-explanatory.
For me it is definitely Police State - I don't think I ever used it, frankly. While there are obviously some civics I use more and some I use less (I prefer Specialist Economies), I think I have used every single one from time to time - even Serfdom if I needed to get Infrastructure fast. Except Police State.
Unless you get Pyramids, you get it very late in game, but even then you would be better off running Representation or even Hereditary Monarchy. The benefits are meagre, unless you plan to go on an endless war.
