I know that some of you think that this bickering and the power-plays is the core of the game, but I really think you don't understand how many of the players consider that the ultimate buzz-kill for them.
I think there is a large difference between bickering and power plays though. Bickering is a buzz kill, power plays though usually tend to invigorate fun for lots of players.
Power plays are things like seceding a duchy, starting a rebellion, banning a set of troublesome nobles or so, stealing half the gold of the realm, turning 90% of your realm over to another realm because you're duke and fed up with the ruler.
Those things I think are valuable for game play.
However, many ppl use bickering to set up power plays which kind of ruins the point.
