The document discusses Jesper Juul's six characteristics of games: rules, quantifiable outcomes, positive and negative values assigned to outcomes, effort required to achieve desired outcomes, emotional attachment to outcomes, and negotiable consequences. It then analyzes whether three games - Pong, Pro Evolution Soccer 2013, and Stronghold - fit these characteristics. Pong and Pro Evolution Soccer 2013 fit all six characteristics, while Stronghold only fits some as there are no real-life consequences negotiated for winning or losing.
