The update 2 was superb and all except the system revolts. They're ok and all for players, not sure if this is the same for all difficulties but AI's behavior of constantly expanding gets themselves wiped out. Instead of having a well developed system decolonize when it reaches maximum threshold for revolution, it should become a minor faction based on the race with the highest pop on the system. These minor factions would start off as having aggressive status and would constantly send out ships to raid other systems until you wipe out that system or make them rejoin you.
