Start on "Begin Journey", end on victory screen? Or end on last click? Or leave it as it is?
I think it should be first click personally. The game will not change at all ( to be fair I'm not sure whether auto turn forces a task on you or not).
I say this because this rule will kind of stop loading a save at the start as you will not know if they did something on the save unless you pay a lot of attention. It is not like you can do much at the start without clicking anyways.
The end needs to be last click. The game was so buggy when I was doing any%, sometimes it will let me end my turn in the city screen, other times it will not make me end until an animation has been complete. I does not seem constant and the time it take to load really can just be treated like a cut scene and after you last click you are not doing anything to the game anyways.
