Okay, here's the deal.
Taking to heart the idea that Diplomacy is a game based on communication, and lots of it, I have (over my time on this site) developed the following philosophy;
At the beginning of the game, send a message to everyone, even if its just a 'hi, lets share info'.
If you think you can affect whats someones actions are, do it.
If it suits you, be purposefully misleading or vague with people across the board that you want to mess, but do make explicit lies that can be disproven.
With allies, potential allies, and even enemies, by clear, detailed, and earnest in your messaging.
I'm always frank, and I'm always trying to convince or talk people my way if I think there is any possibility.
Sometimes, if I feel helpless and upset I neglect to communicate as much as I should, but I don't generally think I'm guilty of that.
Despite all of the above, sometimes I find myself isolated, with no friends (see my 02 Austria death for example of that) and discover that players who rarely speak more than two words to others and never me have masterminded my demise. Somehow.
My question is, does anyone think that talking too much, too desperately, or too suspiciously can alienate people who would normally accept the word of someone who says 'yea sure' to a lengthy alliance proposal?
It seems like a weird concept to me, but it is either that or game History that seems to be alienating people in some of my games.
How do other people formulate thier discussion style in-game?
