Pokemon GO

Pokémon GO remains the most successful real-world mobile game ever, generating over $6 billion in revenue and sustaining 80 million monthly players nearly a decade after launch. Using AR and GPS, Niantic turned the globe into a Pokémon-catching playground, driving unparalleled physical activity: in summer 2016 alone, strangers gathered in parks, businesses became PokeStops, and emergency rooms treated walking-related injuries. This data-rich phenomenon outperforms #2 by maintaining a decade of active engagement, with monthly active users exceeding the average mobile game's lifetime downloads. Its blend of nostalgia and fitness has made walking addictive for millions, proving that mobile gaming can transform habits rather than just fill time.
