Brinksmanship
You knows threats, deterrants and the like
I pre-ordered Diplomacy yesterday and having been playing sporadically since then and so far I like what I'm seeing, one thing I haven't noticed though. is the capability to make threats and the like, and have the AI make threats as well, whether bluff or not. A couple drop down boxes in the diplomacy menu or something could be used to communicate with the AI in a number of ways. For instance "If you don't give me 1000 crystal I'll obliterate planet X" or "You may or may not have noticed, but I have 16 Deliverance Engines and If you don't back off I'll destroy your economy" could give the game a bit of a Cold War aspect. Opinions?
