CICERO is the AI, the game is called "Diplomacy". It's in fact the type of game where you win by convincing others that you aren't a psychopath. (If they believe you more than your opponent then you do well) - specifically, if you backstab/lie too often early on you will always lose, so you have to keep track of social capital and expend it when the time is right such that your enemy won't be alive to make you regret it later
