This presentation summarizes key points from the first part of the book "Reality is Broken" by Jane McGonigal:
1) McGonigal defines the four core traits of games as having a goal, rules, a feedback system, and voluntary participation.
2) She suggests reality lacks sufficient challenges and obstacles compared to games. Games focus our energy with optimism on things we enjoy and are good at.
3) McGonigal cites Tetris as an example of an addictive game due to its intense feedback system and ever-increasing challenges despite being impossible to truly "win".
