Right now it is very barebones, but it is a 0.0.6 alpha so it is to be expected. There are a lot of things that happen on the screen that the player cannot affect at all (characters can own city districts for example, but the player cannot order a character to take or cede control of one such districts directly or indirectly).
Out of several games, I have been able to win only 2. The other I did not lose, however I was rendered unable to reach a conclusion due to rebellions spiraling out of control. In fact, it seems right now there is no way for a city to go back to stable once a rebellion (beginning at 10 unrest) sets in. I have had a city go +125 unrest and into negative population, but otherwise no change - the rebellion keeps on going strong.
I am not exactly sure how the resource system works, but right now it appears that the capital is almost always on fertile grounds and/or rich, and cities with money seem to buy the others' food even when there is no need, leading to starvation and the unrest spirals I spoke before.
Investigators right now are utterly ineffectual. While I do appreciate it when I can convert them to my side, at the moment the challenge seems to be more about winning before rebellions can start.
Not much else to say at the moment, it is possible to play the game from start to finish but there is little to do (and yet that is more than we ever had of TWS, so props to you).
