I have played (and won even!) Diplomacy and I agree about what makes the game fun. But it is interesting that they argue these AI are able to infer people's alliances and reliability based on their actual in-game behavior by modeling how they would act in that scenario and training against that. That's pretty neat, there must be a lot more information encoded in who you choose to support than I'd have thought. It makes me wonder whether the AI would do better or worse than the human attempting to manipulate it. I have this feeling that we will be shocked to discover that the human's inevitable betrayal was inferred based on behavioral changes that fit the betrayal scenario the best. It's not especially hard to imagine even with communication in a fairly reliable way (no misunderstandings from NLP) that an AI might easily learn to guess when a human was acting in a way that didn't... quite... match the behavior of an actual ally. But it would sure help =)
