I just had a though about the way could go about playing the game. Obviously we will try to win, but should we attach some principles to the way we try to achieve victory. For example we could avoid using the "nastier" civics such as slavery and police state to name two. Or for another example we could ban ourselves from razing caputured cites. A principle could be about anything in the game. Personally i am not fussed whether i choose to do something like this but i did think it was worth looking at and discussing amongst ourselves, like the title says, just an idea.
