I learned a lot of my people skills from Diplomacy. It also helped me work out a number of trust issues. Before someone gets worried about the first statement, it does not mean that I am the kind of person who will betray someone - in fact, all my friends will testify that I am unreasonably loyal even under difficult circumstances. What it does mean is that after playing Diplomacy, I became much more self-aware about what I was doing to build friendships and/or relationships, and what others were doing, and also much more flexible at considering things from other people's point of view and therefore constructing deals that actually work for all parties.
