I understand the desire to keep the turn chats as a way to keep it from becoming a succession game, but the turn chats have a tendency to turn it into a cabinet game. Some leaders will prefer to simply issue their instructions during the turn chat, and so the citizens will not know what is being done until it is too late. However, they should not be removed, but each term should be used at the discretion of the president.
As far as the issue with the governor of the first province causing a lack of cohesiveness on expansion, I really only think this will be a problem if we keep a brisk pace. If there is plenty of time for forum discussion and polls, it will be handled very democratically. In fact, every build queue can be voted on until we have a large number of cities. What I am afraid we will end up with, however, are two different proposals regarding expansion/settler production that are voted on and supported by the populace, thus destroying any chance we have of doing well in the initial land grab. One person should be responsible for posting proposals for this effort, and that requires that the domestic leader be allowed to have control over posting build queues, because settlers are necessary for expansion. I also fear that the government will not be prepared for the speed at which the AI will produce settlers and build cities, but that is another story.
I agree the game was much more fun when we were fighting for our existence, but, emperor and deity levels leave very little room for error. Losing is not fun. Even the last game could have been a disaster if Grey Fox was not so skilled at military maneuvers.
