The text discusses the misconceptions around adversarial situations in everyday life, single-player video games, and online gaming. The author argues that interactions in daily life, such as negotiating prices for donuts, are not truly adversarial since both parties generally want a mutually beneficial outcome. Similarly, in single-player games, challenges presented by antagonists (like an evil emperor) are not real adversaries, as they are designed by developers to provide players with a challenge that the player actually desires. While online games like chess
