McGonigal suffers a severe concussion, which significantly impacts her life. As part of her recovery process, she begins to develop the principles that would later become the SuperBetter game. This personal experience drives her to explore the potential of games to promote resilience and recovery from adversity.

SuperBetter, a game designed to build resilience and improve well-being, is officially launched. The game incorporates elements of positive psychology and behavioral science, encouraging players to set goals, complete challenges, and build social support networks. SuperBetter gains widespread attention and becomes a popular tool for personal growth and recovery.

McGonigal publishes the book 'SuperBetter: A Revolutionary Approach to Getting Stronger, Happier, Braver and More Resilient - Or How to Live Impossible Lives'. The book elaborates on the principles and techniques used in the SuperBetter game, providing readers with a comprehensive guide to using gamification to overcome challenges and achieve personal goals.

McGonigal continues to develop and research SuperBetter, refining its features and exploring its potential applications in various fields, including healthcare, education, and workplace wellness. She likely collaborates with researchers and practitioners to evaluate the effectiveness of SuperBetter and to identify new ways to leverage games for positive change.
