Games that create personal wealth. Imagine if every time you spent 99 cents on an extra life in the game "Candy Crush Saga," the funds instead were deposited into your retirement account. No longer a guilty habit, your favorite games would fund your personal savings.

Games that offer college credit and replace internships. In the STEM fields of science, technology, engineering and mathematics, young people could learn important skills and contribute to research just by playing their favorite digital games. As they "level up" in these STEM games, they would unlock real-world credentials that advance their education and careers.

Games that treat mental-health issues. Doctors and therapists could prescribe casual videogames similar to "Angry Birds" or "Clash of Clans" as a first line of attack against depression, anxiety and post-traumatic stress disorder.
