Played two games so far, it is nice that there is now a way for characters to reduce unrest a bit (which helps delay the inevitable, if anything).
My first game ended up in chaos as per 0.0.6 version, since rebellion took over three cities (and then four) before I could get their secrets. So far, if unrest spirals out of control there is still no way to get it back down, even with the unrest reduction in effect.
My second game went much more smoothly - I played against the game's unrest mechanic this time and went for the most unstable cities first. By the time they fell, I had already gotten their secrets and could claim victory.
Nothing new to report on other fronts, I will keep playing and if anything new pops up gameplay-wise I will comment on it. So far the new mechanics do not seem that huge of a change (my agents could still perform their jobs even while in the midst of faction wars, guild wars and other such things).
On an interesting note, the game seemed to freeze when my hard disk usage went up by a background installation, even going as far as giving me a black screen if I minimized and then maximized it. However once the installer got past the heavy load the game resumed just fine... Although it did give me the welcome message again for some reason (bear in mind this was turn 42, I had long closed it).
