“The most important thing in my game designer toolbox is the point system because the point system tells the players what to care about.”
I picked this section because of the correlation to the real world outside of just games. In life we are conditioned by forces out of our control that seem to make up a "point system". For example, in life we are conditioned to believe that money, fame, and materialistic gain are what use to measure success and importance. In reality, these ideas have been pushed forward in order to create a class of workers to fuel capitalism.
