You make it sound better than the Reality. Diplo victory. - Barely improved, still very badly implemented and kind of pointless. Game speed scaling. - Still many of The modes and mechanics dont work properly in different speeds and map sizes. - AI, - Still weak, and uncapable of achieving a domination victory, Even playing alone. The other aystems have been tweaked, I would not say reworked. In most cases I have not noticed any improvement. Honestly, at this point I think they will at most, solve a few bugs, minor balance and maybe add some UI conveniences. I would be surprised if they even make the World Builder work properly.
