The Harvard Program on Negotiation is one of the best resources for identifying negotiation case studies and simulations. Lawrence Susskind explains the power of games:
Role-play simulations can be used in three ways. First, they can be used to give students a chance to experience situations in which they might someday find themselves, offering a quasi-realistic chance to apply what they have learned in class. When used properly, with the help of skilled instructors, role-play simulations can be very effective educational tools. Role-play simulations can also be used as part of a research agenda especially in the negotiation field. In the same way carefully structured laboratory experiments involving students are often used to test psychological hypotheses, role-play simulations, run repeatedly with similar sets of players — some of whom are instructed behind-the-scenes to try different negotiating techniques — are being used to determine the efficacy of various negotiating strategies.
