The most interesting game to me is the recruiting negotiation. When playing the game, my partner and I just focused on getting the maximum personal benefits. We did not understand that compromise would bring higher score for two people as a whole. From the game, I learn that hiring managers should not try to give recruitees as fewer benefits as they can because this will lower new workers' motivation. Then firms will bear loss because of lower labor productivity.
The book Social Influence: The Psychology of Persuasion is my favorite in this class. The influence tactics it describes are really useful for building leadership. So far, I often it hard to influence people, especially someone in higher positions, and I can use these tactics in the future.
