I'm all for the Shogun ways here. A failed bribe should = a chopped off head or at least allow you the option to return the enemy diplomat in a gift bag.

Ah yes anyone remember that good old video of a failed diplomatic mission.

I actually forget the video sequence but the end result was you saw your diplomats head (on a platter?) (in a gift bag?)

Maybe each clan had a different way of returning your emisary.

Bring back the chopping off of diplomats heads
